+  This is a limited shim for ShadowDOM css styling.
+  https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles
+
+  The intention here is to support only the styling features which can be
+  relatively simply implemented. The goal is to allow users to avoid the
+  most obvious pitfalls and do so without compromising performance significantly.
+  For ShadowDOM styling that's not covered here, a set of best practices
+  can be provided that should allow users to accomplish more complex styling.
+
+  The following is a list of specific ShadowDOM styling features and a brief
+  discussion of the approach used to shim.
+
+  Shimmed features:
+
+  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
+  element using the :host rule. To shim this feature, the :host styles are
+  reformatted and prefixed with a given scope name and promoted to a
+  document level stylesheet.
+  For example, given a scope name of .foo, a rule like this:
+
+    :host {
+        background: red;
+      }
     }
-    Xliff.prototype.write = function (messages, locale) {
-        var visitor = new _WriteVisitor();
-        var transUnits = [];
-        messages.forEach(function (message) {
-            var contextTags = [];
-            message.sources.forEach(function (source) {
-                var contextGroupTag = new Tag(_CONTEXT_GROUP_TAG, { purpose: 'location' });
-                contextGroupTag.children.push(new CR(10), new Tag(_CONTEXT_TAG, { 'context-type': 'sourcefile' }, [new Text$2(source.filePath)]), new CR(10), new Tag(_CONTEXT_TAG, { 'context-type': 'linenumber' }, [new Text$2("" + source.startLine)]), new CR(8));
-                contextTags.push(new CR(8), contextGroupTag);
-            });
-            var transUnit = new Tag(_UNIT_TAG, { id: message.id, datatype: 'html' });
-            (_a = transUnit.children).push.apply(_a, Object(tslib__WEBPACK_IMPORTED_MODULE_0__["__spread"])([new CR(8), new Tag(_SOURCE_TAG, {}, visitor.serialize(message.nodes))], contextTags));
-            if (message.description) {
-                transUnit.children.push(new CR(8), new Tag('note', { priority: '1', from: 'description' }, [new Text$2(message.description)]));
-            }
-            if (message.meaning) {
-                transUnit.children.push(new CR(8), new Tag('note', { priority: '1', from: 'meaning' }, [new Text$2(message.meaning)]));
-            }
-            transUnit.children.push(new CR(6));
-            transUnits.push(new CR(6), transUnit);
-            var _a;
-        });
-        var body = new Tag('body', {}, Object(tslib__WEBPACK_IMPORTED_MODULE_0__["__spread"])(transUnits, [new CR(4)]));
-        var file = new Tag('file', {
-            'source-language': locale || _DEFAULT_SOURCE_LANG,
-            datatype: 'plaintext',
-            original: 'ng2.template',
-        }, [new CR(4), body, new CR(2)]);
-        var xliff = new Tag('xliff', { version: _VERSION, xmlns: _XMLNS }, [new CR(2), file, new CR()]);
-        return serialize([
-            new Declaration({ version: '1.0', encoding: 'UTF-8' }), new CR(), xliff, new CR()
-        ]);
+
+  becomes:
+
+    .foo {
+      background: red;
+    }
+
+  * encapsulation: Styles defined within ShadowDOM, apply only to
+  dom inside the ShadowDOM. Polymer uses one of two techniques to implement
+  this feature.
+
+  By default, rules are prefixed with the host element tag name
+  as a descendant selector. This ensures styling does not leak out of the 'top'
+  of the element's ShadowDOM. For example,
+
+  div {
+      font-weight: bold;
+    }
+
+  becomes:
+
+  x-foo div {
+      font-weight: bold;
+    }
+
+  becomes:
+
+
+  Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
+  selectors are scoped by adding an attribute selector suffix to each
+  simple selector that contains the host element tag name. Each element
+  in the element's ShadowDOM template is also given the scope attribute.
+  Thus, these rules match only elements that have the scope attribute.
+  For example, given a scope name of x-foo, a rule like this:
+
+    div {
+      font-weight: bold;
+    }
+
+  becomes:
+
+    div[x-foo] {
+      font-weight: bold;
+    }
+
+  Note that elements that are dynamically added to a scope must have the scope
+  selector added to them manually.
+
+  * upper/lower bound encapsulation: Styles which are defined outside a
+  shadowRoot should not cross the ShadowDOM boundary and should not apply
+  inside a shadowRoot.
+
+  This styling behavior is not emulated. Some possible ways to do this that
+  were rejected due to complexity and/or performance concerns include: (1) reset
+  every possible property for every possible selector for a given scope name;
+  (2) re-implement css in javascript.
+
+  As an alternative, users should make sure to use selectors
+  specific to the scope in which they are working.
+
+  * ::distributed: This behavior is not emulated. It's often not necessary
+  to style the contents of a specific insertion point and instead, descendants
+  of the host element can be styled selectively. Users can also create an
+  extra node around an insertion point and style that node's contents
+  via descendent selectors. For example, with a shadowRoot like this:
+
+    <style>
+      ::content(div) {
+        background: red;
+      }
+    </style>
+    <content></content>
+
+  could become:
+
+    <style>
+      / *@polyfill .content-container div * /
+      ::content(div) {
+        background: red;
+      }
+    </style>
+    <div class="content-container">
+      <content></content>
+    </div>
+
+  Note the use of @polyfill in the comment above a ShadowDOM specific style
+  declaration. This is a directive to the styling shim to use the selector
+  in comments in lieu of the next selector when running under polyfill.

+/**
+ * This array represents the DOM schema. It encodes inheritance, properties, and events.
+ *
+ * ## Overview
+ *
+ * Each line represents one kind of element. The `element_inheritance` and properties are joined
+ * using `element_inheritance|properties` syntax.
+ *
+ * ## Element Inheritance
+ *
+ * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
+ * Here the individual elements are separated by `,` (commas). Every element in the list
+ * has identical properties.
+ *
+ * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
+ * specified then `""` (blank) element is assumed.
+ *
+ * NOTE: The blank element inherits from root `[Element]` element, the super element of all
+ * elements.
+ *
+ * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
+ *
+ * ## Properties
+ *
+ * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
+ * by a special character designating its type:
+ *
+ * - (no prefix): property is a string.
+ * - `*`: property represents an event.
+ * - `!`: property is a boolean.
+ * - `#`: property is a number.
+ * - `%`: property is an object.
+ *
+ * ## Query
+ *
+ * The class creates an internal squas representation which allows to easily answer the query of
+ * if a given property exist on a given element.
+ *
+ * NOTE: We don't yet support querying for types or events.
+ * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
+ *       see dom_element_schema_registry_spec.ts

 /**
- * This array represents the DOM schema. It encodes inheritance, properties, and events.
- *
- * ## Overview
- *
- * Each line represents one kind of element. The `element_inheritance` and properties are joined
- * using `element_inheritance|properties` syntax.
- *
- * ## Element Inheritance
- *
- * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
- * Here the individual elements are separated by `,` (commas). Every element in the list
- * has identical properties.
- *
- * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
- * specified then `""` (blank) element is assumed.
- *
- * NOTE: The blank element inherits from root `[Element]` element, the super element of all
- * elements.
- *
- * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
- *
- * ## Properties
- *
- * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
- * by a special character designating its type:
- *
- * - (no prefix): property is a string.
- * - `*`: property represents an event.
- * - `!`: property is a boolean.
- * - `#`: property is a number.
- * - `%`: property is an object.
- *
- * ## Query
- *
- * The class creates an internal squas representation which allows to easily answer the query of
- * if a given property exist on a given element.
- *
- * NOTE: We don't yet support querying for types or events.
- * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
- *       see dom_element_schema_registry_spec.ts
+ * A container for translated messages

-/*
-  This is a limited shim for ShadowDOM css styling.
-  https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles
-
-  The intention here is to support only the styling features which can be
-  relatively simply implemented. The goal is to allow users to avoid the
-  most obvious pitfalls and do so without compromising performance significantly.
-  For ShadowDOM styling that's not covered here, a set of best practices
-  can be provided that should allow users to accomplish more complex styling.
-
-  The following is a list of specific ShadowDOM styling features and a brief
-  discussion of the approach used to shim.
-
-  Shimmed features:
-
-  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
-  element using the :host rule. To shim this feature, the :host styles are
-  reformatted and prefixed with a given scope name and promoted to a
-  document level stylesheet.
-  For example, given a scope name of .foo, a rule like this:
-
-    :host {
-        background: red;
-      }
-    }
-
-  becomes:
-
-    .foo {
-      background: red;
-    }
-
-  * encapsulation: Styles defined within ShadowDOM, apply only to
-  dom inside the ShadowDOM. Polymer uses one of two techniques to implement
-  this feature.
-
-  By default, rules are prefixed with the host element tag name
-  as a descendant selector. This ensures styling does not leak out of the 'top'
-  of the element's ShadowDOM. For example,
-
-  div {
-      font-weight: bold;
-    }
-
-  becomes:
-
-  x-foo div {
-      font-weight: bold;
-    }
-
-  becomes:
-
-
-  Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
-  selectors are scoped by adding an attribute selector suffix to each
-  simple selector that contains the host element tag name. Each element
-  in the element's ShadowDOM template is also given the scope attribute.
-  Thus, these rules match only elements that have the scope attribute.
-  For example, given a scope name of x-foo, a rule like this:
-
-    div {
-      font-weight: bold;
-    }
-
-  becomes:
-
-    div[x-foo] {
-      font-weight: bold;
-    }
-
-  Note that elements that are dynamically added to a scope must have the scope
-  selector added to them manually.
-
-  * upper/lower bound encapsulation: Styles which are defined outside a
-  shadowRoot should not cross the ShadowDOM boundary and should not apply
-  inside a shadowRoot.
-
-  This styling behavior is not emulated. Some possible ways to do this that
-  were rejected due to complexity and/or performance concerns include: (1) reset
-  every possible property for every possible selector for a given scope name;
-  (2) re-implement css in javascript.
-
-  As an alternative, users should make sure to use selectors
-  specific to the scope in which they are working.
-
-  * ::distributed: This behavior is not emulated. It's often not necessary
-  to style the contents of a specific insertion point and instead, descendants
-  of the host element can be styled selectively. Users can also create an
-  extra node around an insertion point and style that node's contents
-  via descendent selectors. For example, with a shadowRoot like this:
-
-    <style>
-      ::content(div) {
-        background: red;
-      }
-    </style>
-    <content></content>
-
-  could become:
-
-    <style>
-      / *@polyfill .content-container div * /
-      ::content(div) {
-        background: red;
-      }
-    </style>
-    <div class="content-container">
-      <content></content>
-    </div>
-
-  Note the use of @polyfill in the comment above a ShadowDOM specific style
-  declaration. This is a directive to the styling shim to use the selector
-  in comments in lieu of the next selector when running under polyfill.

+ * A regular expression for breaking a URI into its component parts.
+ *
+ * {@link http://www.gbiv.com/protocols/uri/rfc/rfc3986.html#RFC2234} says
+ * As the "first-match-wins" algorithm is identical to the "greedy"
+ * disambiguation method used by POSIX regular expressions, it is natural and
+ * commonplace to use a regular expression for parsing the potential five
+ * components of a URI reference.
+ *
+ * The following line is the regular expression for breaking-down a
+ * well-formed URI reference into its components.
+ *
+ * <pre>
+ * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
+ *  12            3  4          5       6  7        8 9
+ * </pre>
+ *
+ * The numbers in the second line above are only to assist readability; they
+ * indicate the reference points for each subexpression (i.e., each paired
+ * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
+ * For example, matching the above expression to
+ * <pre>
+ *     http://www.ics.uci.edu/pub/ietf/uri/#Related
+ * </pre>
+ * results in the following subexpression matches:
+ * <pre>
+ *    $1 = http:
+ *    $2 = http
+ *    $3 = //www.ics.uci.edu
+ *    $4 = www.ics.uci.edu
+ *    $5 = /pub/ietf/uri/
+ *    $6 = <undefined>
+ *    $7 = <undefined>
+ *    $8 = #Related
+ *    $9 = Related
+ * </pre>
+ * where <undefined> indicates that the component is not present, as is the
+ * case for the query component in the above example. Therefore, we can
+ * determine the value of the five components as
+ * <pre>
+ *    scheme    = $2
+ *    authority = $4
+ *    path      = $5
+ *    query     = $7
+ *    fragment  = $9
+ * </pre>
+ *
+ * The regular expression has been modified slightly to expose the
+ * userInfo, domain, and port separately from the authority.
+ * The modified version yields
+ * <pre>
+ *    $1 = http              scheme
+ *    $2 = <undefined>       userInfo -\
+ *    $3 = www.ics.uci.edu   domain     | authority
+ *    $4 = <undefined>       port     -/
+ *    $5 = /pub/ietf/uri/    path
+ *    $6 = <undefined>       query without ?
+ *    $7 = Related           fragment without #

+ *
+ * Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a

+ *
+ * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by

+ * ```
+ *
+ * When creating an `InjectionToken`, you can optionally specify a factory function which returns
+ * (possibly by creating) a default value of the parameterized type `T`. This sets up the
+ * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
+ * application's root injector. If the factory function, which takes zero arguments, needs to inject
+ * dependencies, it can do so using the `inject` function. See below for an example.
+ *
+ * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
+ * overrides the above behavior and marks the token as belonging to a particular `@NgModule`. As

- * An internal module of the Angular compiler that begins with component types,

  *
- * @security  When compiling templates at runtime, you must ensure that the entire template comes
- * from a trusted source. Attacker-controlled data introduced by a template could expose your
- * application to XSS risks.  For more detail, see the [Security Guide](http://g.co/ng/security).
+ * This method is used with `factory` functions which are generated as part of
+ * `defineDirective` or `defineComponent`. The method retrieves the static value
+ * of an attribute. (Dynamic attributes are not supported since they are not resolved
+ *  at the time of injection and can change over time.)
+ *
+ * # Example
+ * Given:
+ * ```
+ * @Component(...)
+ * class MyComponent {
+ *   constructor(@Attribute('title') title: string) { ... }
+ * }
+ * ```
+ * When instantiated with
+ * ```
+ * <my-component title="Hello"></my-component>
+ * ```

+ * Then factory method generated is:

- *
- * Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a
- * runtime representation) such as when injecting an interface, callable type, array or

- *
- * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by

- * ```
- *
- * When creating an `InjectionToken`, you can optionally specify a factory function which returns
- * (possibly by creating) a default value of the parameterized type `T`. This sets up the
- * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
- * application's root injector. If the factory function, which takes zero arguments, needs to inject
- * dependencies, it can do so using the `inject` function. See below for an example.
- *
- * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
- * overrides the above behavior and marks the token as belonging to a particular `@NgModule`. As

- * Component decorator and metadata.
- *
- * @usageNotes
- *
- * ### Using animations
- *
- * The following snippet shows an animation trigger in a component's
- * metadata. The trigger is attached to an element in the component's
- * template, using "@_trigger_name_", and a state expression that is evaluated
- * at run time to determine whether the animation should start.
- *
- * ```typescript
- * @Component({
- *   selector: 'animation-cmp',
- *   templateUrl: 'animation-cmp.html',
- *   animations: [
- *     trigger('myTriggerName', [
- *       state('on', style({ opacity: 1 }),
- *       state('off', style({ opacity: 0 }),
- *       transition('on => off', [
- *         animate("1s")
- *       ])
- *     ])
- *   ]
- * })
- * ```
- *
- * ```html
- * <!-- animation-cmp.html -->
- * <div @myTriggerName="expression">...</div>
- * ```
- *
- * ### Preserving whitespace
- *
- * Removing whitespace can greatly reduce AOT-generated code size, and speed up view creation.
- * As of Angular 6, default for `preserveWhitespaces` is false (whitespace is removed).
- * To change the default setting for all components in your application, set
- * the `preserveWhitespaces` option of the AOT compiler.
- *
- * Current implementation removes whitespace characters as follows:
- * - Trims all whitespaces at the beginning and the end of a template.
- * - Removes whitespace-only text nodes. For example,
- * `<button>Action 1</button>  <button>Action 2</button>` becomes
- * `<button>Action 1</button><button>Action 2</button>`.
- * - Replaces a series of whitespace characters in text nodes with a single space.
- * For example, `<span>\n some text\n</span>` becomes `<span> some text </span>`.
- * - Does NOT alter text nodes inside HTML tags such as `<pre>` or `<textarea>`,
- * where whitespace characters are significant.
- *
- * Note that these transformations can influence DOM nodes layout, although impact
- * should be minimal.
- *
- * You can override the default behavior to preserve whitespace characters
- * in certain fragments of a template. For example, you can exclude an entire
- * DOM sub-tree by using the `ngPreserveWhitespaces` attribute:
- *
- * ```html
- * <div ngPreserveWhitespaces>
- *     whitespaces are preserved here
- *     <span>    and here </span>
- * </div>
- * ```
- *
- * You can force a single space to be preserved in a text node by using `&ngsp;`,
- * which is replaced with a space character by Angular's template
- * compiler:
- *
- * ```html
- * <a>Spaces</a>&ngsp;<a>between</a>&ngsp;<a>links.</a>
- * <!-->compiled to be equivalent to:</>
- *  <a>Spaces</a> <a>between</a> <a>links.</a>
- * ```
- *
- * Note that sequences of `&ngsp;` are still collapsed to just one space character when
- * the `preserveWhitespaces` option is set to `false`.
- *
- * ```html
- * <a>before</a>&ngsp;&ngsp;&ngsp;<a>after</a>
- * <!-->compiled to be equivalent to:</>
- *  <a>Spaces</a> <a>between</a> <a>links.</a>
- * ```
- *
- * To preserve sequences of whitespace characters, use the
- * `ngPreserveWhitespaces` attribute.

- * A ReflectiveDependency injection container used for instantiating objects and resolving

- * Notice, we don't use the `new` operator because we explicitly want to have the `Injector`

- * @deprecated from v5 - slow and brings in a lot of code, Use `Injector.create` instead.

+     * check every five seconds.
+     *
+     * See {@link ChangeDetectorRef#detach detach} for more information.

- *
- * In the following example, `Zippy` alternatively emits `open` and `close` events when its
- * title gets clicked:
- *
- * ```
- * @Component({
- *   selector: 'zippy',
- *   template: `
- *   <div class="zippy">
- *     <div (click)="toggle()">Toggle</div>
- *     <div [hidden]="!visible">
- *       <ng-content></ng-content>
- *     </div>
- *  </div>`})
- * export class Zippy {
- *   visible: boolean = true;
- *   @Output() open: EventEmitter<any> = new EventEmitter();
- *   @Output() close: EventEmitter<any> = new EventEmitter();
- *
- *   toggle() {
- *     this.visible = !this.visible;
- *     if (this.visible) {
- *       this.open.emit(null);
- *     } else {
- *       this.close.emit(null);
- *     }
- *   }
- * }
- * ```
+ * This file introduces series of globally accessible debug tools
+ * to allow for the Angular debugging story to function.
  *
- * The events payload can be accessed by the parameter `$event` on the components output event
- * handler:
- *
- * ```
- * <zippy (open)="onOpen($event)" (close)="onClose($event)"></zippy>
- * ```
- *
- * ### Notes
- *
- * Uses Rx.Observable but provides an adapter to make it work as specified here:
- * https://github.com/jhusain/observable-spec
+ * To see this in action run the following command:
  *
- * Once a reference implementation of the spec is available, switch to it.
+ *   bazel run --define=compile=aot
+ *   //packages/core/test/bundling/todo:devserver

-/**
- * Represents an Angular View.
- *
- * <!-- TODO: move the next two paragraphs to the dev guide -->
- * A View is a fundamental building block of the application UI. It is the smallest grouping of
- * Elements which are created and destroyed together.
- *
- * Properties of elements in a View can change, but the structure (number and order) of elements in
- * a View cannot. Changing the structure of Elements can only be done by inserting, moving or
- * removing nested Views via a `ViewContainerRef`. Each View can contain many View Containers.
- * <!-- /TODO -->
- *
- * @usageNotes
- * ### Example
- *
- * Given this template...
- *
- * ```
- * Count: {{items.length}}
- * <ul>
- *   <li *ngFor="let  item of items">{{item}}</li>
- * </ul>
- * ```
- *
- * We have two `TemplateRef`s:
- *
- * Outer `TemplateRef`:
- *
- * ```
- * Count: {{items.length}}
- * <ul>
- *   <ng-template ngFor let-item [ngForOf]="items"></ng-template>
- * </ul>
- * ```
- *
- * Inner `TemplateRef`:
- *
- * ```
- *   <li>{{item}}</li>
- * ```
- *
- * Notice that the original template is broken down into two separate `TemplateRef`s.
- *
- * The outer/inner `TemplateRef`s are then assembled into views like so:
- *
- * ```
- * <!-- ViewRef: outer-0 -->
- * Count: 2
- * <ul>
- *   <ng-template view-container-ref></ng-template>
- *   <!-- ViewRef: inner-1 --><li>first</li><!-- /ViewRef: inner-1 -->
- *   <!-- ViewRef: inner-2 --><li>second</li><!-- /ViewRef: inner-2 -->
- * </ul>
- * <!-- /ViewRef: outer-0 -->
- * ```

-/**
- * A pattern that recognizes a commonly useful subset of URLs that are safe.
- *
- * This regular expression matches a subset of URLs that will not cause script
- * execution if used in URL context within a HTML document. Specifically, this
- * regular expression matches if (comment from here on and regex copied from
- * Soy's EscapingConventions):
- * (1) Either a protocol in a whitelist (http, https, mailto or ftp).
- * (2) or no protocol.  A protocol must be followed by a colon. The below
- *     allows that by allowing colons only after one of the characters [/?#].
- *     A colon after a hash (#) must be in the fragment.
- *     Otherwise, a colon after a (?) must be in a query.
- *     Otherwise, a colon after a single solidus (/) must be in a path.
- *     Otherwise, a colon after a double solidus (//) must be in the authority
- *     (before port).
- *
- * The pattern disallows &, used in HTML entity declarations before
- * one of the characters in [/?#]. This disallows HTML entities used in the
- * protocol name, which should never happen, e.g. "h&#116;tp" for "http".
- * It also disallows HTML entities in the first path part of a relative path,
- * e.g. "foo&lt;bar/baz".  Our existing escaping functions should not produce
- * that. More importantly, it disallows masking of a colon,
- * e.g. "javascript&#58;...".
- *
- * This regular expression was taken from the Closure sanitization library.

+/**
+ * A ReflectiveDependency injection container used for instantiating objects and resolving
+ * dependencies.
+ *
+ * An `Injector` is a replacement for a `new` operator, which can automatically resolve the
+ * constructor dependencies.
+ *
+ * In typical use, application code asks for the dependencies in the constructor and they are
+ * resolved by the `Injector`.
+ *
+ * @usageNotes
+ * ### Example
+ *
+ * The following example creates an `Injector` configured to create `Engine` and `Car`.
+ *
+ * ```typescript
+ * @Injectable()
+ * class Engine {
+ * }
+ *
+ * @Injectable()
+ * class Car {
+ *   constructor(public engine:Engine) {}
+ * }
+ *
+ * var injector = ReflectiveInjector.resolveAndCreate([Car, Engine]);
+ * var car = injector.get(Car);
+ * expect(car instanceof Car).toBe(true);
+ * expect(car.engine instanceof Engine).toBe(true);
+ * ```
+ *
+ * Notice, we don't use the `new` operator because we explicitly want to have the `Injector`
+ * resolve all of the object's dependencies automatically.
+ *
+ * @deprecated from v5 - slow and brings in a lot of code, Use `Injector.create` instead.
+ * @publicApi

-// This function calls the ngAfterContentCheck, ngAfterContentInit,
-// ngAfterViewCheck, and ngAfterViewInit lifecycle hooks (depending on the node
-// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are
-// called during a pre-order traversal of the view tree (that is calling the
-// parent hooks before the child hooks) these events are sent in using a
-// post-order traversal of the tree (children before parents). This changes the
-// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the
-// expected nodeIndex which a ngOnInit should be called. When sending
-// ngAfterContentInit and ngAfterViewInit it is the expected count of
-// ngAfterContentInit or ngAfterViewInit methods that have been called. This
-// ensure that despite being called recursively or after picking up after an
-// exception, the ngAfterContentInit or ngAfterViewInit will be called on the
-// correct nodes. Consider for example, the following (where E is an element
-// and D is a directive)
-//  Tree:       pre-order index  post-order index
-//    E1        0                6
-//      E2      1                1
-//       D3     2                0
-//      E4      3                5
-//       E5     4                4
-//        E6    5                2
-//        E7    6                3
-// As can be seen, the post-order index has an unclear relationship to the
-// pre-order index (postOrderIndex === preOrderIndex - parentCount +
-// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit
-// are stable (will be the same for the same view regardless of exceptions or
-// recursion) we just need to count them which will roughly correspond to the
-// post-order index (it skips elements and directives that do not have
-// lifecycle hooks).
-//
-// For example, if an exception is raised in the E6.onAfterViewInit() the
-// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to
-// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will
-// not have their ngAfterViewInit() called but, starting with E7, the rest of
-// the view will begin getting ngAfterViewInit() called until a check and
-// pass is complete.
-//
-// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()
-// indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected
-// initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.
-// D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.
-// When the recursion returns the initIndex will be 7 so E1 is skipped as it
-// has already been called in the recursively called checkAnUpdateView().

+/**
+ * Base class for Angular Views, provides change detection functionality.
+ * A change-detection tree collects all views that are to be checked for changes.
+ * Use the methods to add and remove views from the tree, initiate change-detection,
+ * and explicitly mark views as _dirty_, meaning that they have changed and need to be rerendered.
+ *
+ * @usageNotes
+ *
+ * The following examples demonstrate how to modify default change-detection behavior
+ * to perform explicit detection when needed.
+ *
+ * ### Use `markForCheck()` with `CheckOnce` strategy
+ *
+ * The following example sets the `OnPush` change-detection strategy for a component
+ * (`CheckOnce`, rather than the default `CheckAlways`), then forces a second check
+ * after an interval. See [live demo](http://plnkr.co/edit/GC512b?p=preview).
+ *
+ * <code-example path="core/ts/change_detect/change-detection.ts"
+ * region="mark-for-check"></code-example>
+ *
+ * ### Detach change detector to limit how often check occurs
+ *
+ * The following example defines a component with a large list of read-only data
+ * that is expected to change constantly, many times per second.
+ * To improve performance, we want to check and update the list
+ * less often than the changes actually occur. To do that, we detach
+ * the component's change detector and perform an explicit local check every five seconds.
+ *
+ * <code-example path="core/ts/change_detect/change-detection.ts" region="detach"></code-example>
+ *
+ *
+ * ### Reattaching a detached component
+ *
+ * The following example creates a component displaying live data.
+ * The component detaches its change detector from the main change detector tree
+ * when the `live` property is set to false, and reattaches it when the property
+ * becomes true.
+ *
+ * <code-example path="core/ts/change_detect/change-detection.ts" region="reattach"></code-example>

+// called during a pre-order traversal of the view tree (that is calling the
+// parent hooks before the child hooks) these events are sent in using a
+// post-order traversal of the tree (children before parents). This changes the
+// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the
+// expected nodeIndex which a ngOnInit should be called. When sending
+// ngAfterContentInit and ngAfterViewInit it is the expected count of
+// ngAfterContentInit or ngAfterViewInit methods that have been called. This
+// ensure that despite being called recursively or after picking up after an
+// exception, the ngAfterContentInit or ngAfterViewInit will be called on the
+// correct nodes. Consider for example, the following (where E is an element
+// and D is a directive)
+//  Tree:       pre-order index  post-order index
+//    E1        0                6
+//      E2      1                1
+//       D3     2                0
+//      E4      3                5
+//       E5     4                4
+//        E6    5                2
+//        E7    6                3
+// As can be seen, the post-order index has an unclear relationship to the
+// pre-order index (postOrderIndex === preOrderIndex - parentCount +
+// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit
+// are stable (will be the same for the same view regardless of exceptions or
+// recursion) we just need to count them which will roughly correspond to the
+// post-order index (it skips elements and directives that do not have
+// lifecycle hooks).
+//
+// For example, if an exception is raised in the E6.onAfterViewInit() the
+// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to
+// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will
+// not have their ngAfterViewInit() called but, starting with E7, the rest of
+// the view will begin getting ngAfterViewInit() called until a check and
+// pass is complete.
+//
+// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()
+// indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected
+// initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.
+// D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.
+// When the recursion returns the initIndex will be 7 so E1 is skipped as it

  *
- * ### How to use select controls with form directives
+ * ### Using select controls in a template-driven form
  *
  * To use a select in a template-driven form, simply add an `ngModel` and a `name`
  * attribute to the main `<select>` tag.
  *
- * If your option values are simple strings, you can bind to the normal `value` property
- * on the option.  If your option values happen to be objects (and you'd like to save the
- * selection in your form as an object), use `ngValue` instead:
- *
  * {@example forms/ts/selectControl/select_control_example.ts region='Component'}
  *
- * In reactive forms, you'll also want to add your form directive (`formControlName` or
- * `formControl`) on the main `<select>` tag. Like in the former example, you have the
- * choice of binding to the  `value` or `ngValue` property on the select's options.
- *
- * {@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}
- *
- * ### Caveat: Option selection

  *
- * Syncs a standalone `FormControl` instance to a form control element.
- *
- * This directive ensures that any values written to the `FormControl`
- * instance programmatically will be written to the DOM element (model -> view). Conversely,
- * any values written to the DOM element through user input will be reflected in the
- * `FormControl` instance (view -> model).
- *
- * Use this directive if you'd like to create and manage a `FormControl` instance directly.
- * Simply create a `FormControl`, save it to your component class, and pass it into the
- * `FormControlDirective`.
- *
- * This directive is designed to be used as a standalone control.  Unlike `FormControlName`,
- * it does not require that your `FormControl` instance be part of any parent
- * `FormGroup`, and it won't be registered to any `FormGroupDirective` that
- * exists above it.
- *
- * **Get the value**: the `value` property is always synced and available on the
- * `FormControl` instance. See a full list of available properties in
- * `AbstractControl`.
+ * @see [Reactive Forms Guide](guide/reactive-forms)
+ * @see `FormControl`
+ * @see `AbstractControl`
  *
- * **Set the value**: You can pass in an initial value when instantiating the `FormControl`,
- * or you can set it programmatically later using {@link AbstractControl#setValue setValue} or
- * {@link AbstractControl#patchValue patchValue}.
+ * @usageNotes
  *
- * **Listen to value**: If you want to listen to changes in the value of the control, you can
- * subscribe to the {@link AbstractControl#valueChanges valueChanges} event.  You can also listen to
- * {@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is
- * re-calculated.
+ * ### Registering a single form control
  *
- * ### Example
+ * The following examples shows how to register a standalone control and set its value.
  *
  * {@example forms/ts/simpleFormControl/simple_form_control_example.ts region='Component'}

- * * **npm package**: `@angular/forms`
- *
- * * **NgModule**: `ReactiveFormsModule`
- *
  * ### Use with ngModel
  *
  * Support for using the `ngModel` input property and `ngModelChange` event with reactive
  * form directives has been deprecated in Angular v6 and will be removed in Angular v7.
  *
  * Now deprecated:

  * Syncs a `FormControl` in an existing `FormGroup` to a form control
  * element by name.
  *
- * This directive ensures that any values written to the `FormControl`
- * instance programmatically will be written to the DOM element (model -> view). Conversely,
- * any values written to the DOM element through user input will be reflected in the
- * `FormControl` instance (view -> model).
- *
- * This directive is designed to be used with a parent `FormGroupDirective` (selector:
- * `[formGroup]`).
- *
- * It accepts the string name of the `FormControl` instance you want to
- * link, and will look for a `FormControl` registered with that name in the
- * closest `FormGroup` or `FormArray` above it.
- *
- * **Access the control**: You can access the `FormControl` associated with
- * this directive by using the {@link AbstractControl#get get} method.
- * Ex: `this.form.get('first');`
- *
- * **Get value**: the `value` property is always synced and available on the `FormControl`.
- * See a full list of available properties in `AbstractControl`.
- *
- *  **Set value**: You can set an initial value for the control when instantiating the
- *  `FormControl`, or you can set it programmatically later using
- *  {@link AbstractControl#setValue setValue} or {@link AbstractControl#patchValue patchValue}.
+ * @see [Reactive Forms Guide](guide/reactive-forms)
+ * @see `FormControl`
+ * @see `AbstractControl`
  *
- * **Listen to value**: If you want to listen to changes in the value of the control, you can
- * subscribe to the {@link AbstractControl#valueChanges valueChanges} event.  You can also listen to
- * {@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is
- * re-calculated.
+ * @usageNotes
  *
- * ### Example
+ * ### Register `FormControl` within a group
  *
- * In this example, we create form controls for first name and last name.
+ * The following example shows how to register multiple form controls within a form group
+ * and set their value.
  *
  * {@example forms/ts/simpleFormGroup/simple_form_group_example.ts region='Component'}

The context\n * for each instantiated template inherits from the outer context with the given loop variable\n * set to the current item from the iterable.\n *\n * ### Local Variables\n *\n * `NgForOf` provides several exported values that can be aliased to local variables:\n *\n * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).\n * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is\n * more complex then a property access, for example when using the async pipe (`userStreams |\n * async`).\n * - `index: number`: The index of the current item in the iterable.\n * - `first: boolean`: True when the item is the first item in the iterable.\n * - `last: boolean`: True when the item is the last item in the iterable.\n * - `even: boolean`: True when the item has an even index in the iterable.\n * - `odd: boolean`: True when the item has an odd index in the iterable.\n *\n * ```\n * <li *ngFor=\"let user of userObservable | async as users; index as i; first as isFirst\">\n *    {{i}}/{{users.length}}. {{user}} <span *ngIf=\"isFirst\">default</span>\n * </li>\n * ```\n *\n * ### Change Propagation\n *\n * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n * * Otherwise, the DOM element for that item will remain the same.\n *\n * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n * those changes in the DOM. This has important implications for animations and any stateful\n * controls (such as `<input>` elements which accept user input) that are present. Inserted rows can\n * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state\n * such as user input.\n *\n * It is possible for the identities of elements in the iterator to change while the data does not.\n * This can happen, for example, if the iterator produced from an RPC to the server, and that\n * RPC is re-run. Even if the data hasn't changed, the second response will produce objects with\n * different identities, and Angular will tear down the entire DOM and rebuild it (as if all old\n * elements were deleted and all new elements inserted). This is an expensive operation and should\n * be avoided if possible.\n *\n * To customize the default tracking algorithm, `NgForOf` supports `trackBy` option.\n * `trackBy` takes a function which has two arguments: `index` and `item`.\n * If `trackBy` is given, Angular tracks changes by the return value of the function.\n *\n * ### Syntax\n *\n * - `<li *ngFor=\"let item of items; index as i; trackBy: trackByFn\">...</li>`\n *\n * With `<ng-template>` element:\n *\n * ```\n * <ng-template ngFor let-item [ngForOf]=\"items\" let-i=\"index\" [ngForTrackBy]=\"trackByFn\">\n *   <li>...</li>\n * </ng-template>\n * ```\n *\n * ### Example\n *\n * See a [live demo](http://plnkr.co/edit/KVuXxDp0qinGDyo307QW?p=preview) for a more detailed\n * example.\n *\n *\n */\nvar NgForOf = /** @class */ (function () {\n    function NgForOf(_viewContainer, _template, _differs) {\n        this._viewContainer = _viewContainer;\n        this._template = _template;\n        this._differs = _differs;\n        this._differ = null;\n    }\n    Object.defineProperty(NgForOf.prototype, \"ngForTrackBy\", {\n        get: function () { return this._trackByFn; },\n        set: function (fn) {\n            if (isDevMode() && fn != null && typeof fn !== 'function') {\n                // TODO(vicb): use a log service once there is a public one available\n                if (console && console.warn) {\n                    console.warn(\"trackBy must be a function, but received \" + JSON.stringify(fn) + \". \" +\n                        \"See https://angular.io/docs/ts/latest/api/common/index/NgFor-directive.html#!#change-propagation for more information.\");\n                }\n            }\n            this._trackByFn = fn;\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgForOf.prototype, \"ngForTemplate\", {\n        set: function (value) {\n            // TODO(TS2.1): make TemplateRef<Partial<NgForRowOf<T>>> once we move to TS v2.1\n            // The current type is too restrictive; a template that just uses index, for example,\n            // should be acceptable.\n            if (value) {\n                this._template = value;\n            }\n        },\n        enumerable: true,\n        configurable: true\n    });\n    NgForOf.prototype.ngOnChanges = function (changes) {\n        if ('ngForOf' in changes) {\n            // React on ngForOf changes only once all inputs have been initialized\n            var value = changes['ngForOf'].currentValue;\n            if (!this._differ && value) {\n                try {\n                    this._differ = this._differs.find(value).create(this.ngForTrackBy);\n                }\n                catch (e) {\n                    throw new Error(\"Cannot find a differ supporting object '\" + value + \"' of type '\" + getTypeNameForDebugging(value) + \"'.

Typically the:\n *  - `then` template is the inline template of `ngIf` unless bound to a different value.\n *  - `else` template is blank unless it is bound.\n *\n * ## Most common usage\n *\n * The most common usage of the `ngIf` directive is to conditionally show the inline template as\n * seen in this example:\n * {@example common/ngIf/ts/module.ts region='NgIfSimple'}\n *\n * ## Showing an alternative template using `else`\n *\n * If it is necessary to display a template when the `expression` is falsy use the `else` template\n * binding as shown. Note that the `else` binding points to a `<ng-template>` labeled `#elseBlock`.\n * The template can be defined anywhere in the component view but is typically placed right after\n * `ngIf` for readability.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfElse'}\n *\n * ## Using non-inlined `then` template\n *\n * Usually the `then` template is the inlined template of the `ngIf`, but it can be changed using\n * a binding (just like `else`). Because `then` and `else` are bindings, the template references can\n * change at runtime as shown in this example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}\n *\n * ## Storing conditional result in a variable\n *\n * A common pattern is that we need to show a set of properties from the same object. If the\n * object is undefined, then we have to use the safe-traversal-operator `?.` to guard against\n * dereferencing a `null` value. This is especially the case when waiting on async data such as\n * when using the `async` pipe as shown in following example:\n *\n * ```\n * Hello {{ (userStream|async)?.last }}, {{ (userStream|async)?.first }}!\n * ```\n *\n * There are several inefficiencies in the above example:\n *  - We create multiple subscriptions on `userStream`. One for each `async` pipe, or two in the\n *    example above.\n *  - We cannot display an alternative screen while waiting for the data to arrive asynchronously.\n *  - We have to use the safe-traversal-operator `?.` to access properties, which is cumbersome.\n *  - We have to place the `async` pipe in parenthesis.\n *\n * A better way to do this is to use `ngIf` and store the result of the condition in a local\n * variable as shown in the the example below:\n *\n * {@example common/ngIf/ts/module.ts region='NgIfAs'}\n *\n * Notice that:\n *  - We use only one `async` pipe and hence only one subscription gets created.\n *  - `ngIf` stores the result of the `userStream|async` in the local variable `user`.\n *  - The local `user` can then be bound repeatedly in a more efficient way.\n *  - No need to use the safe-traversal-operator `?.` to access properties as `ngIf` will only\n *    display the data if `userStream` returns a value.\n *  - We can display an alternative template while waiting for the data.\n *\n * ### Syntax\n *\n * Simple form:\n * - `<div *ngIf=\"condition\">...</div>`\n * - `<ng-template [ngIf]=\"condition\"><div>...</div></ng-template>`\n *\n * Form with an else block:\n * ```\n * <div *ngIf=\"condition; else elseBlock\">...</div>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * Form with a `then` and `else` block:\n * ```\n * <div *ngIf=\"condition; then thenBlock else elseBlock\"></div>\n * <ng-template #thenBlock>...</ng-template>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * Form with storing the value locally:\n * ```\n * <div *ngIf=\"condition as value; else elseBlock\">{{value}}</div>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n *\n */\nvar NgIf = /** @class */ (function () {\n    function NgIf(_viewContainer, templateRef) {\n        this._viewContainer = _viewContainer;\n        this._context = new NgIfContext();\n        this._thenTemplateRef = null;\n        this._elseTemplateRef = null;\n        this._thenViewRef = null;\n        this._elseViewRef = null;\n        this._thenTemplateRef = templateRef;\n    }\n    Object.defineProperty(NgIf.prototype, \"ngIf\", {\n        set: function (condition) {\n            this._context.$implicit = this._context.ngIf = condition;\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgIf.prototype, \"ngIfThen\", {\n        set: function (templateRef) {\n            assertTemplate('ngIfThen', templateRef);\n            this._thenTemplateRef = templateRef;\n            this._thenViewRef = null; // clear previous view if any.\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgIf.prototype, \"ngIfElse\", {\n        set: function (templateRef) {\n            assertTemplate('ngIfElse', templateRef);\n            this._elseTemplateRef = templateRef;\n            this._elseViewRef = null; // clear previous view if any.\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    NgIf.prototype._updateView = function () {\n        if (this._context.$implicit) {\n            if (!this._thenViewRef) {\n                this._viewContainer.clear();\n                this._elseViewRef = null;\n                if (this._thenTemplateRef) {\n                    this._thenViewRef =\n                        this._viewContainer.createEmbeddedView(this._thenTemplateRef, this._context);\n                }\n            }\n        }\n        else {\n            if (!this._elseViewRef) {\n                this._viewContainer.clear();\n                this._thenViewRef = null;\n                if (this._elseTemplateRef) {\n                    this._elseViewRef =\n                        this._viewContainer.createEmbeddedView(this._elseTemplateRef, this._context);\n                }\n            }\n        }\n    };\n    NgIf.decorators = [\n        { type: Directive, args: [{ selector: '[ngIf]' },] }\n    ];\n    /** @nocollapse */\n    NgIf.ctorParameters = function () { return [\n        { type: ViewContainerRef },\n        { type: TemplateRef }\n    ]; };\n    NgIf.propDecorators = {\n        ngIf: [{ type: Input }],\n        ngIfThen: [{ type: Input }],\n        ngIfElse: [{ type: Input }]\n    };\n    return NgIf;\n}());\nvar NgIfContext = /** @class */ (function () {\n    function NgIfContext() {\n        this.$implicit = null;\n        this.ngIf = null;\n    }\n    return NgIfContext;\n}());\nfunction assertTemplate(property, templateRef) {\n    var isTemplateRefOrNull = !!(!templateRef || templateRef.createEmbeddedView);\n    if (!isTemplateRefOrNull) {\n        throw new Error(property + \" must be a TemplateRef, but received '\" + ɵstringify(templateRef) + \"'.\");\n    }\n}\n\n/**\n * @license\n * Copyright Google Inc.

* Note that timezone correction is not applied to an ISO string that has no time component, such as \"2016-09-19\"\n *\n * ### Format examples\n *\n * These examples transform a date into various formats,\n * assuming that `dateObj` is a JavaScript `Date` object for\n * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,\n * given in the local time for the `en-US` locale.\n *\n * ```\n * {{ dateObj | date }}               // output is 'Jun 15, 2015'\n * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'\n * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'\n * {{ dateObj | date:'mmss' }}        // output is '43:11'\n * ```\n *\n * ### Usage example\n *\n * The following component uses a date pipe to display the current date in different formats.\n *\n * ```\n * @Component({\n *  selector: 'date-pipe',\n *  template: `<div>\n *    <p>Today is {{today | date}}</p>\n *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>\n *    <p>The time is {{today | date:'h:mm a z'}}</p>\n *  </div>`\n * })\n * // Get the current date and time as a date-time value.\n * export class DatePipeComponent {\n *   today: number = Date.now();\n * }\n * ```\n *\n */\n// clang-format on\nvar DatePipe = /** @class */ (function () {\n    function DatePipe(locale) {\n        this.locale = locale;\n    }\n    /**\n     * @param value The date

The `element_inheritance` and properties are joined\n * using `element_inheritance|properties` syntax.\n *\n * ## Element Inheritance\n *\n * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.\n * Here the individual elements are separated by `,` (commas). Every element in the list\n * has identical properties.\n *\n * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is\n * specified then `\"\"` (blank) element is assumed.\n *\n * NOTE: The blank element inherits from root `[Element]` element, the super element of all\n * elements.\n *\n * NOTE an element prefix such as `:svg:` has no special meaning to the schema.\n *\n * ## Properties\n *\n * Each element has a set of properties separated by `,` (commas). Each property can be prefixed\n * by a special character designating its type:\n *\n * - (no prefix): property is a string.\n * - `*`: property represents an event.\n * - `!`: property is a boolean.\n * - `#`: property is a number.\n * - `%`: property is an object.\n *\n * ## Query\n *\n * The class creates an internal squas representation which allows to easily answer the query of\n * if a given property exist on a given element.\n *\n * NOTE: We don't yet support querying for types or events.\n * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,\n *       see dom_element_schema_registry_spec.ts\n */\n// =================================================================================================\n// =================================================================================================\n// =========== S T O P   -  S T O P   -  S T O P   -  S T O P   -  S T O P   -  S T O P  ===========\n// =================================================================================================\n// =================================================================================================\n//\n//                       DO NOT EDIT THIS DOM SCHEMA WITHOUT A SECURITY REVIEW!\n//\n// Newly added properties must be security reviewed and assigned an appropriate SecurityContext in\n// dom_security_schema.ts.

The goal is to allow users to avoid the\n  most obvious pitfalls and do so without compromising performance significantly.\n  For ShadowDOM styling that's not covered here, a set of best practices\n  can be provided that should allow users to accomplish more complex styling.\n\n  The following is a list of specific ShadowDOM styling features and a brief\n  discussion of the approach used to shim.\n\n  Shimmed features:\n\n  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n  element using the :host rule. To shim this feature, the :host styles are\n  reformatted and prefixed with a given scope name and promoted to a\n  document level stylesheet.\n  For example, given a scope name of .foo, a rule like this:\n\n    :host {\n        background: red;\n      }\n    }\n\n  becomes:\n\n    .foo {\n      background: red;\n    }\n\n  * encapsulation: Styles defined within ShadowDOM, apply only to\n  dom inside the ShadowDOM. Polymer uses one of two techniques to implement\n  this feature.\n\n  By default, rules are prefixed with the host element tag name\n  as a descendant selector. This ensures styling does not leak out of the 'top'\n  of the element's ShadowDOM. For example,\n\n  div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n  x-foo div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n\n  Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then\n  selectors are scoped by adding an attribute selector suffix to each\n  simple selector that contains the host element tag name. Each element\n  in the element's ShadowDOM template is also given the scope attribute.\n  Thus, these rules match only elements that have the scope attribute.\n  For example, given a scope name of x-foo, a rule like this:\n\n    div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n    div[x-foo] {\n      font-weight: bold;\n    }\n\n  Note that elements that are dynamically added to a scope must have the scope\n  selector added to them manually.\n\n  * upper/lower bound encapsulation: Styles which are defined outside a\n  shadowRoot should not cross the ShadowDOM boundary and should not apply\n  inside a shadowRoot.\n\n  This styling behavior is not emulated. Some possible ways to do this that\n  were rejected due to complexity and/or performance concerns include: (1) reset\n  every possible property for every possible selector for a given scope name;\n  (2) re-implement css in javascript.\n\n  As an alternative, users should make sure to use selectors\n  specific to the scope in which they are working.\n\n  * ::distributed: This behavior is not emulated. It's often not necessary\n  to style the contents of a specific insertion point and instead, descendants\n  of the host element can be styled selectively. Users can also create an\n  extra node around an insertion point and style that node's contents\n  via descendent selectors. For example, with a shadowRoot like this:\n\n    <style>\n      ::content(div) {\n        background: red;\n      }\n    </style>\n    <content></content>\n\n  could become:\n\n    <style>\n      / *@polyfill .content-container div * /\n      ::content(div) {\n        background: red;\n      }\n    </style>\n    <div class=\"content-container\">\n      <content></content>\n    </div>\n\n  Note the use of @polyfill in the comment above a ShadowDOM specific style\n  declaration. This is a directive to the styling shim to use the selector\n  in comments in lieu of the next selector when running under polyfill.\n*/\nvar ShadowCss = /** @class */ (function () {\n    function ShadowCss() {\n        this.strictStyling = true;\n    }\n    /*\n    * Shim some cssText with the given selector.

The trigger is attached to an element in the component's\n * template, using \"@_trigger_name_\", and a state expression that is evaluated\n * at run time to determine whether the animation should start.\n *\n * ```typescript\n * @Component({\n *   selector: 'animation-cmp',\n *   templateUrl: 'animation-cmp.html',\n *   animations: [\n *     trigger('myTriggerName', [\n *       state('on', style({ opacity: 1 }),\n *       state('off', style({ opacity: 0 }),\n *       transition('on => off', [\n *         animate(\"1s\")\n *       ])\n *     ])\n *   ]\n * })\n * ```\n *\n * ```html\n * <!-- animation-cmp.html -->\n * <div @myTriggerName=\"expression\">...</div>\n * ```\n *\n * ### Preserving whitespace\n *\n * Removing whitespace can greatly reduce AOT-generated code size, and speed up view creation.\n * As of Angular 6, default for `preserveWhitespaces` is false (whitespace is removed).\n * To change the default setting for all components in your application, set\n * the `preserveWhitespaces` option of the AOT compiler.\n *\n * Current implementation removes whitespace characters as follows:\n * - Trims all whitespaces at the beginning and the end of a template.\n * - Removes whitespace-only text nodes. For example,\n * `<button>Action 1</button>  <button>Action 2</button>` becomes\n * `<button>Action 1</button><button>Action 2</button>`.\n * - Replaces a series of whitespace characters in text nodes with a single space.\n * For example, `<span>\\n some text\\n</span>` becomes `<span> some text </span>`.\n * - Does NOT alter text nodes inside HTML tags such as `<pre>` or `<textarea>`,\n * where whitespace characters are significant.\n *\n * Note that these transformations can influence DOM nodes layout, although impact\n * should be minimal.\n *\n * You can override the default behavior to preserve whitespace characters\n * in certain fragments of a template. For example, you can exclude an entire\n * DOM sub-tree by using the `ngPreserveWhitespaces` attribute:\n *\n * ```html\n * <div ngPreserveWhitespaces>\n *     whitespaces are preserved here\n *     <span>    and here </span>\n * </div>\n * ```\n *\n * You can force a single space to be preserved in a text node by using `&ngsp;`,\n * which is replaced with a space character by Angular's template\n * compiler:\n *\n * ```html\n * <a>Spaces</a>&ngsp;<a>between</a>&ngsp;<a>links.</a>\n * <!-->compiled to be equivalent to:</>\n *  <a>Spaces</a> <a>between</a> <a>links.</a>\n * ```\n *\n * Note that sequences of `&ngsp;` are still collapsed to just one space character when\n * the `preserveWhitespaces` option is set to `false`.\n *\n * ```html\n * <a>before</a>&ngsp;&ngsp;&ngsp;<a>after</a>\n * <!-->compiled to be equivalent to:</>\n *  <a>Spaces</a> <a>between</a> <a>links.</a>\n * ```\n *\n * To preserve sequences of whitespace characters, use the\n * `ngPreserveWhitespaces` attribute.\n *\n * @Annotation\n */\nvar Component = makeDecorator('Component', function (c) {\n    if (c === void 0) { c = {}; }\n    return (__assign({ changeDetection: ChangeDetectionStrategy.Default }, c));\n}, Directive);\n/**\n *\n *\n * @Annotation\n */\nvar Pipe = makeDecorator('Pipe', function (p) { return (__assign({ pure: true }, p)); });\n/**\n *\n * @Annotation\n */\nvar Input = makePropDecorator('Input', function (bindingPropertyName) { return ({ bindingPropertyName: bindingPropertyName }); });\n/**\n *\n * @Annotation\n */\nvar Output = makePropDecorator('Output', function (bindingPropertyName) { return ({ bindingPropertyName: bindingPropertyName }); });\n/**\n *\n * @Annotation\n */\nvar HostBinding = makePropDecorator('HostBinding', function (hostPropertyName) { return ({ hostPropertyName: hostPropertyName }); });\n/**\n * Binds a CSS event to a host listener and supplies configuration metadata.\n * Angular invokes the supplied handler method when the host element emits the specified event,\n * and updates the bound element with the result.\n * If the handler method returns false, applies `preventDefault` on the bound element.\n *\n * @usageNotes\n *\n * The following example declares a directive\n * that attaches a click listener to a button and counts clicks.\n *\n * ```\n * @Directive({selector: 'button[counting]'})\n * class CountClicks {\n *   numberOfClicks = 0;\n *\n *   @HostListener('click', ['$event.target'])\n *   onClick(btn) {\n *     console.log('button', btn, 'number of clicks:', this.numberOfClicks++);\n *  }\n * }\n *\n * @Component({\n *   selector: 'app',\n *   template: '<button counting>Increment</button>',\n * })\n * class App {}\n * ```\n *\n * @Annotation\n */\nvar HostListener = makePropDecorator('HostListener', function (eventName, args) { return ({ eventName: eventName, args: args }); });\n\n/**\n * @license\n * Copyright Google Inc.

hooks (depending on the node\n// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are\n// called during a pre-order traversal of the view tree (that is calling the\n// parent hooks before the child hooks) these events are sent in using a\n// post-order traversal of the tree (children before parents). This changes the\n// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the\n// expected nodeIndex which a ngOnInit should be called. When sending\n// ngAfterContentInit and ngAfterViewInit it is the expected count of\n// ngAfterContentInit or ngAfterViewInit methods that have been called. This\n// ensure that despite being called recursively or after picking up after an\n// exception, the ngAfterContentInit or ngAfterViewInit will be called on the\n// correct nodes. Consider for example, the following (where E is an element\n// and D is a directive)\n//  Tree:       pre-order index  post-order index\n//    E1        0                6\n//      E2      1                1\n//       D3     2                0\n//      E4      3                5\n//       E5     4                4\n//        E6    5                2\n//        E7    6                3\n// As can be seen, the post-order index has an unclear relationship to the\n// pre-order index (postOrderIndex === preOrderIndex - parentCount +\n// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit\n// are stable (will be the same for the same view regardless of exceptions or\n// recursion) we just need to count them which will roughly correspond to the\n// post-order index (it skips elements and directives that do not have\n// lifecycle hooks).\n//\n// For example, if an exception is raised in the E6.onAfterViewInit() the\n// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to\n// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will\n// not have their ngAfterViewInit() called but, starting with E7, the rest of\n// the view will begin getting ngAfterViewInit() called until a check and\n// pass is complete.\n//\n// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()\n// indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected\n// initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.\n// D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.\n// When the recursion returns the initIndex will be 7 so E1 is skipped as it\n// has already been called in the recursively called checkAnUpdateView().\nfunction callLifecycleHooksChildrenFirst(view, lifecycles) {\n    if (!(view.def.nodeFlags & lifecycles)) {\n        return;\n    }\n    var nodes = view.def.nodes;\n    var initIndex = 0;\n    for (var i = 0; i < nodes.length; i++) {\n        var nodeDef = nodes[i];\n        var parent_1 = nodeDef.parent;\n        if (!parent_1 && nodeDef.flags & lifecycles) {\n            // matching root node (e.g. a pipe)\n            callProviderLifecycles(view, i, nodeDef.flags & lifecycles, initIndex++);\n        }\n        if ((nodeDef.childFlags & lifecycles) === 0) {\n            // no child matches one of the lifecycles\n            i += nodeDef.childCount;\n        }\n        while (parent_1 && (parent_1.flags & 1 /* TypeElement */) &&\n            i === parent_1.nodeIndex + parent_1.childCount) {\n            // last child of an element\n            if (parent_1.directChildFlags & lifecycles) {\n                initIndex = callElementProvidersLifecycles(view, parent_1, lifecycles, initIndex);\n            }\n            parent_1 = parent_1.parent;\n        }\n    }\n}\nfunction callElementProvidersLifecycles(view, elDef, lifecycles, initIndex) {\n    for (var i = elDef.nodeIndex + 1; i <= elDef.nodeIndex + elDef.childCount; i++) {\n        var nodeDef = view.def.nodes[i];\n        if (nodeDef.flags & lifecycles) {\n            callProviderLifecycles(view, i, nodeDef.flags & lifecycles, initIndex++);\n        }\n        // only visit direct children\n        i += nodeDef.childCount;\n    }\n    return initIndex;\n}\nfunction callProviderLifecycles(view, index, lifecycles, initIndex) {\n    var providerData = asProviderData(view, index);\n    if (!providerData) {\n        return;\n    }\n    var provider = providerData.instance;\n    if (!provider) {\n        return;\n    }\n    Services.setCurrentNode(view, index);\n    if (lifecycles & 1048576 /* AfterContentInit */ &&\n        shouldCallLifecycleInitHook(view, 512 /* InitState_CallingAfterContentInit */, initIndex)) {\n        provider.ngAfterContentInit();\n    }\n    if (lifecycles & 2097152 /* AfterContentChecked */) {\n        provider.ngAfterContentChecked();\n    }\n    if (lifecycles & 4194304 /* AfterViewInit */ &&\n        shouldCallLifecycleInitHook(view, 768 /* InitState_CallingAfterViewInit */, initIndex)) {\n        provider.ngAfterViewInit();\n    }\n    if (lifecycles & 8388608 /* AfterViewChecked */) {\n        provider.ngAfterViewChecked();\n    }\n    if (lifecycles & 131072 /* OnDestroy */) {\n        provider.ngOnDestroy();\n    }\n}\n\n/**\n * @license\n * Copyright Google Inc.

You do\n * **not** need to add a special selector to activate it.\n *\n * ### How to use select controls with form directives\n *\n * To use a select in a template-driven form, simply add an `ngModel` and a `name`\n * attribute to the main `<select>` tag.\n *\n * If your option values are simple strings, you can bind to the normal `value` property\n * on the option.  If your option values happen to be objects (and you'd like to save the\n * selection in your form as an object), use `ngValue` instead:\n *\n * {@example forms/ts/selectControl/select_control_example.ts region='Component'}\n *\n * In reactive forms, you'll also want to add your form directive (`formControlName` or\n * `formControl`) on the main `<select>` tag. Like in the former example, you have the\n * choice of binding to the  `value` or `ngValue` property on the select's options.\n *\n * {@example forms/ts/reactiveSelectControl/reactive_select_control_example.ts region='Component'}\n *\n * ### Caveat: Option selection\n *\n * Angular uses object identity to select option. It's possible for the identities of items\n * to change while the data does not. This can happen, for example, if the items are produced\n * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the\n * second response will produce objects with different identities.\n *\n * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.\n * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.\n * If `compareWith` is given, Angular selects option by the return value of the function.\n *\n * #### Syntax\n *\n * ```\n * <select [compareWith]=\"compareFn\"  [(ngModel)]=\"selectedCountries\">\n *     <option *ngFor=\"let country of countries\" [ngValue]=\"country\">\n *         {{country.name}}\n *     </option>\n * </select>\n *\n * compareFn(c1: Country, c2: Country): boolean {\n *     return c1 && c2 ? c1.id === c2.id : c1 === c2;\n * }\n * ```\n *\n * Note: We listen to the 'change' event because 'input' events aren't fired\n * for selects in Firefox and IE:\n * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350\n * https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4660045/\n *\n * * **npm package**: `@angular/forms`\n *\n *\n */\nvar SelectControlValueAccessor = /** @class */ (function () {\n    function SelectControlValueAccessor(_renderer, _elementRef) {\n        this._renderer = _renderer;\n        this._elementRef = _elementRef;\n        /** @internal */\n        this._optionMap = new Map();\n        /** @internal */\n        this._idCounter = 0;\n        this.onChange = function (_) { };\n        this.onTouched = function () { };\n        this._compareWith = ɵlooseIdentical;\n    }\n    Object.defineProperty(SelectControlValueAccessor.prototype, \"compareWith\", {\n        set: function (fn) {\n            if (typeof fn !== 'function') {\n                throw new Error(\"compareWith must be a function, but received \" + JSON.stringify(fn));\n            }\n            this._compareWith = fn;\n        },\n        enumerable: true,\n        configurable: true\n    });\n    SelectControlValueAccessor.prototype.writeValue = function (value) {\n        this.value = value;\n        var id = this._getOptionId(value);\n        if (id == null) {\n            this._renderer.setProperty(this._elementRef.nativeElement, 'selectedIndex', -1);\n        }\n        var valueString = _buildValueString(id, value);\n        this._renderer.setProperty(this._elementRef.nativeElement, 'value', valueString);\n    };\n    SelectControlValueAccessor.prototype.registerOnChange = function (fn) {\n        var _this = this;\n        this.onChange = function (valueString) {\n            _this.value = _this._getOptionValue(valueString);\n            fn(_this.value);\n        };\n    };\n    SelectControlValueAccessor.prototype.registerOnTouched = function (fn) { this.onTouched = fn; };\n    SelectControlValueAccessor.prototype.setDisabledState = function (isDisabled) {\n        this._renderer.setProperty(this._elementRef.nativeElement, 'disabled', isDisabled);\n    };\n    /** @internal */\n    SelectControlValueAccessor.prototype._registerOption = function () { return (this._idCounter++).toString(); };\n    /** @internal */\n    SelectControlValueAccessor.prototype._getOptionId = function (value) {\n        try {\n            for (var _a = __values(Array.from(this._optionMap.keys())), _b = _a.next(); !_b.done; _b = _a.next()) {\n                var id = _b.value;\n                if (this._compareWith(this._optionMap.get(id), value))\n                    return id;\n            }\n        }\n        catch (e_1_1) { e_1 = { error: e_1_1 }; }\n        finally {\n            try {\n                if (_b && !_b.done && (_c = _a.return)) _c.call(_a);\n            }\n            finally { if (e_1) throw e_1.error; }\n        }\n        return null;\n        var e_1, _c;\n    };\n    /** @internal */\n    SelectControlValueAccessor.prototype._getOptionValue = function (valueString) {\n        var id = _extractId(valueString);\n        return this._optionMap.has(id) ?

All you need is the\n * `ngModel` selector to activate it.\n *\n * It accepts a domain model as an optional `Input`. If you have a one-way binding\n * to `ngModel` with `[]` syntax, changing the value of the domain model in the component\n * class will set the value in the view. If you have a two-way binding with `[()]` syntax\n * (also known as 'banana-box syntax'), the value in the UI will always be synced back to\n * the domain model in your class as well.\n *\n * If you wish to inspect the properties of the associated `FormControl` (like\n * validity state), you can also export the directive into a local template variable using\n * `ngModel` as the key (ex: `#myVar=\"ngModel\"`). You can then access the control using the\n * directive's `control` property, but most properties you'll need (like `valid` and `dirty`)\n * will fall through to the control anyway, so you can access them directly. You can see a\n * full list of properties directly available in `AbstractControlDirective`.\n *\n * The following is an example of a simple standalone control using `ngModel`:\n *\n * {@example forms/ts/simpleNgModel/simple_ng_model_example.ts region='Component'}\n *\n * When using the `ngModel` within `<form>` tags, you'll also need to supply a `name` attribute\n * so that the control can be registered with the parent form under that name.\n *\n * It's worth noting that in the context of a parent form, you often can skip one-way or\n * two-way binding because the parent form will sync the value for you. You can access\n * its properties by exporting it into a local template variable using `ngForm` (ex:\n * `#f=\"ngForm\"`). Then you can pass it where it needs to go on submit.\n *\n * If you do need to populate initial values into your form, using a one-way binding for\n * `ngModel` tends to be sufficient as long as you use the exported form's value rather\n * than the domain model's value on submit.\n *\n * Take a look at an example of using `ngModel` within a form:\n *\n * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}\n *\n * To see `ngModel` examples with different form control types, see:\n *\n * * Radio buttons: `RadioControlValueAccessor`\n * * Selects: `SelectControlValueAccessor`\n *\n * **npm package**: `@angular/forms`\n *\n * **NgModule**: `FormsModule`\n *\n *\n */\nvar NgModel = /** @class */ (function (_super) {\n    __extends(NgModel, _super);\n    function NgModel(parent, validators, asyncValidators, valueAccessors) {\n        var _this = _super.call(this) || this;\n        _this.control = new FormControl();\n        /** @internal */\n        _this._registered = false;\n        _this.update = new EventEmitter();\n        _this._parent = parent;\n        _this._rawValidators = validators || [];\n        _this._rawAsyncValidators = asyncValidators || [];\n        _this.valueAccessor = selectValueAccessor(_this, valueAccessors);\n        return _this;\n    }\n    NgModel.prototype.ngOnChanges = function (changes) {\n        this._checkForErrors();\n        if (!this._registered)\n            this._setUpControl();\n        if ('isDisabled' in changes) {\n            this._updateDisabled(changes);\n        }\n        if (isPropertyUpdated(changes, this.viewModel)) {\n            this._updateValue(this.model);\n            this.viewModel = this.model;\n        }\n    };\n    NgModel.prototype.ngOnDestroy = function () { this.formDirective && this.formDirective.removeControl(this); };\n    Object.defineProperty(NgModel.prototype, \"path\", {\n        get: function () {\n            return this._parent ?

Conversely,\n * any values written to the DOM element through user input will be reflected in the\n * `FormControl` instance (view -> model).\n *\n * Use this directive if you'd like to create and manage a `FormControl` instance directly.\n * Simply create a `FormControl`, save it to your component class, and pass it into the\n * `FormControlDirective`.\n *\n * This directive is designed to be used as a standalone control.  Unlike `FormControlName`,\n * it does not require that your `FormControl` instance be part of any parent\n * `FormGroup`, and it won't be registered to any `FormGroupDirective` that\n * exists above it.\n *\n * **Get the value**: the `value` property is always synced and available on the\n * `FormControl` instance. See a full list of available properties in\n * `AbstractControl`.\n *\n * **Set the value**: You can pass in an initial value when instantiating the `FormControl`,\n * or you can set it programmatically later using {@link AbstractControl#setValue setValue} or\n * {@link AbstractControl#patchValue patchValue}.\n *\n * **Listen to value**: If you want to listen to changes in the value of the control, you can\n * subscribe to the {@link AbstractControl#valueChanges valueChanges} event.  You can also listen to\n * {@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is\n * re-calculated.\n *\n * ### Example\n *\n * {@example forms/ts/simpleFormControl/simple_form_control_example.ts region='Component'}\n *\n * * **npm package**: `@angular/forms`\n *\n * * **NgModule**: `ReactiveFormsModule`\n *\n * ### Use with ngModel\n *\n * Support for using the `ngModel` input property and `ngModelChange` event with reactive\n * form directives has been deprecated in Angular v6 and will be removed in Angular v7.\n *\n * Now deprecated:\n * ```html\n * <input [formControl]=\"control\" [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * This has been deprecated for a few reasons. First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <input [formControl]=\"control\">\n * ```\n *\n * ```ts\n * this.control.setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n *\n */\nvar FormControlDirective = /** @class */ (function (_super) {\n    __extends(FormControlDirective, _super);\n    function FormControlDirective(validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this = _super.call(this) || this;\n        _this._ngModelWarningConfig = _ngModelWarningConfig;\n        /** @deprecated as of v6 */\n        _this.update = new EventEmitter();\n        /**\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular FormControlDirective instance.

You can also listen to\n * {@link AbstractControl#statusChanges statusChanges} to be notified when the validation status is\n * re-calculated.\n *\n * ### Example\n *\n * In this example, we create form controls for first name and last name.\n *\n * {@example forms/ts/simpleFormGroup/simple_form_group_example.ts region='Component'}\n *\n * To see `formControlName` examples with different form control types, see:\n *\n * * Radio buttons: `RadioControlValueAccessor`\n * * Selects: `SelectControlValueAccessor`\n *\n * **npm package**: `@angular/forms`\n *\n * **NgModule**: `ReactiveFormsModule`\n *\n * ### Use with ngModel\n *\n * Support for using the `ngModel` input property and `ngModelChange` event with reactive\n * form directives has been deprecated in Angular v6 and will be removed in Angular v7.\n *\n * Now deprecated:\n * ```html\n * <form [formGroup]=\"form\">\n *   <input formControlName=\"first\" [(ngModel)]=\"value\">\n * </form>\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * This has been deprecated for a few reasons. First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <form [formGroup]=\"form\">\n *   <input formControlName=\"first\">\n * </form>\n * ```\n *\n * ```ts\n * this.form.get('first').setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n *\n */\nvar FormControlName = /** @class */ (function (_super) {\n    __extends(FormControlName, _super);\n    function FormControlName(parent, validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this = _super.call(this) || this;\n        _this._ngModelWarningConfig = _ngModelWarningConfig;\n        _this._added = false;\n        /** @deprecated as of v6 */\n        _this.update = new EventEmitter();\n        /**\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular FormControlName instance.

The context\n * for each instantiated template inherits from the outer context with the given loop variable\n * set to the current item from the iterable.\n *\n * @usageNotes\n *\n * ### Local Variables\n *\n * `NgForOf` provides several exported values that can be aliased to local variables:\n *\n * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).\n * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is\n * more complex then a property access, for example when using the async pipe (`userStreams |\n * async`).\n * - `index: number`: The index of the current item in the iterable.\n * - `first: boolean`: True when the item is the first item in the iterable.\n * - `last: boolean`: True when the item is the last item in the iterable.\n * - `even: boolean`: True when the item has an even index in the iterable.\n * - `odd: boolean`: True when the item has an odd index in the iterable.\n *\n * ```\n * <li *ngFor=\"let user of userObservable | async as users; index as i; first as isFirst\">\n *    {{i}}/{{users.length}}. {{user}} <span *ngIf=\"isFirst\">default</span>\n * </li>\n * ```\n *\n * ### Change Propagation\n *\n * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n * * Otherwise, the DOM element for that item will remain the same.\n *\n * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n * those changes in the DOM. This has important implications for animations and any stateful\n * controls (such as `<input>` elements which accept user input) that are present. Inserted rows can\n * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state\n * such as user input.\n *\n * It is possible for the identities of elements in the iterator to change while the data does not.\n * This can happen, for example, if the iterator produced from an RPC to the server, and that\n * RPC is re-run.

Typically the:\n *  - `then` template is the inline template of `ngIf` unless bound to a different value.\n *  - `else` template is blank unless it is bound.\n *\n *\n * @usageNotes\n *\n * ### Most common usage\n *\n * The most common usage of the `ngIf` directive is to conditionally show the inline template as\n * seen in this example:\n * {@example common/ngIf/ts/module.ts region='NgIfSimple'}\n *\n * ### Showing an alternative template using `else`\n *\n * If it is necessary to display a template when the `expression` is falsy use the `else` template\n * binding as shown. Note that the `else` binding points to a `<ng-template>` labeled `#elseBlock`.\n * The template can be defined anywhere in the component view but is typically placed right after\n * `ngIf` for readability.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfElse'}\n *\n * ### Using non-inlined `then` template\n *\n * Usually the `then` template is the inlined template of the `ngIf`, but it can be changed using\n * a binding (just like `else`). Because `then` and `else` are bindings, the template references can\n * change at runtime as shown in this example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}\n *\n * ### Storing conditional result in a variable\n *\n * A common pattern is that we need to show a set of properties from the same object. If the\n * object is undefined, then we have to use the safe-traversal-operator `?.` to guard against\n * dereferencing a `null` value. This is especially the case when waiting on async data such as\n * when using the `async` pipe as shown in following example:\n *\n * ```\n * Hello {{ (userStream|async)?.last }}, {{ (userStream|async)?.first }}!\n * ```\n *\n * There are several inefficiencies in the above example:\n *  - We create multiple subscriptions on `userStream`. One for each `async` pipe, or two in the\n *    example above.\n *  - We cannot display an alternative screen while waiting for the data to arrive asynchronously.\n *  - We have to use the safe-traversal-operator `?.` to access properties, which is cumbersome.\n *  - We have to place the `async` pipe in parenthesis.\n *\n * A better way to do this is to use `ngIf` and store the result of the condition in a local\n * variable as shown in the the example below:\n *\n * {@example common/ngIf/ts/module.ts region='NgIfAs'}\n *\n * Notice that:\n *  - We use only one `async` pipe and hence only one subscription gets created.\n *  - `ngIf` stores the result of the `userStream|async` in the local variable `user`.\n *  - The local `user` can then be bound repeatedly in a more efficient way.\n *  - No need to use the safe-traversal-operator `?.` to access properties as `ngIf` will only\n *    display the data if `userStream` returns a value.\n *  - We can display an alternative template while waiting for the data.\n *\n * ### Syntax\n *\n * Simple form:\n * - `<div *ngIf=\"condition\">...</div>`\n * - `<ng-template [ngIf]=\"condition\"><div>...</div></ng-template>`\n *\n * Form with an else block:\n * ```\n * <div *ngIf=\"condition; else elseBlock\">...</div>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * Form with a `then` and `else` block:\n * ```\n * <div *ngIf=\"condition; then thenBlock else elseBlock\"></div>\n * <ng-template #thenBlock>...</ng-template>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * Form with storing the value locally:\n * ```\n * <div *ngIf=\"condition as value; else elseBlock\">{{value}}</div>\n * <ng-template #elseBlock>...</ng-template>\n * ```\n *\n * @ngModule CommonModule\n * @publicApi\n */\nvar NgIf = /** @class */ (function () {\n    function NgIf(_viewContainer, templateRef) {\n        this._viewContainer = _viewContainer;\n        this._context = new NgIfContext();\n        this._thenTemplateRef = null;\n        this._elseTemplateRef = null;\n        this._thenViewRef = null;\n        this._elseViewRef = null;\n        this._thenTemplateRef = templateRef;\n    }\n    Object.defineProperty(NgIf.prototype, \"ngIf\", {\n        set: function (condition) {\n            this._context.$implicit = this._context.ngIf = condition;\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgIf.prototype, \"ngIfThen\", {\n        set: function (templateRef) {\n            assertTemplate('ngIfThen', templateRef);\n            this._thenTemplateRef = templateRef;\n            this._thenViewRef = null; // clear previous view if any.\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    Object.defineProperty(NgIf.prototype, \"ngIfElse\", {\n        set: function (templateRef) {\n            assertTemplate('ngIfElse', templateRef);\n            this._elseTemplateRef = templateRef;\n            this._elseViewRef = null; // clear previous view if any.\n            this._updateView();\n        },\n        enumerable: true,\n        configurable: true\n    });\n    NgIf.prototype._updateView = function () {\n        if (this._context.$implicit) {\n            if (!this._thenViewRef) {\n                this._viewContainer.clear();\n                this._elseViewRef = null;\n                if (this._thenTemplateRef) {\n                    this._thenViewRef =\n                        this._viewContainer.createEmbeddedView(this._thenTemplateRef, this._context);\n                }\n            }\n        }\n        else {\n            if (!this._elseViewRef) {\n                this._viewContainer.clear();\n                this._thenViewRef = null;\n                if (this._elseTemplateRef) {\n                    this._elseViewRef =\n                        this._viewContainer.createEmbeddedView(this._elseTemplateRef, this._context);\n                }\n            }\n        }\n    };\n    /**\n     * Assert the correct type of the expression bound to the `ngIf` input within the template.\n     *\n     * The presence of this method is a signal to the Ivy template type check compiler that when the\n     * `NgIf` structural directive renders its template, the type of the expression bound to `ngIf`\n     * should be narrowed in some way.

* Note that timezone correction is not applied to an ISO string that has no time component, such as \"2016-09-19\"\n *\n * ### Format examples\n *\n * These examples transform a date into various formats,\n * assuming that `dateObj` is a JavaScript `Date` object for\n * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,\n * given in the local time for the `en-US` locale.\n *\n * ```\n * {{ dateObj | date }}               // output is 'Jun 15, 2015'\n * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'\n * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'\n * {{ dateObj | date:'mmss' }}        // output is '43:11'\n * ```\n *\n * ### Usage example\n *\n * The following component uses a date pipe to display the current date in different formats.\n *\n * ```\n * @Component({\n *  selector: 'date-pipe',\n *  template: `<div>\n *    <p>Today is {{today | date}}</p>\n *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>\n *    <p>The time is {{today | date:'h:mm a z'}}</p>\n *  </div>`\n * })\n * // Get the current date and time as a date-time value.\n * export class DatePipeComponent {\n *   today: number = Date.now();\n * }\n * ```\n *\n * @publicApi\n */\n// clang-format on\nvar DatePipe = /** @class */ (function () {\n    function DatePipe(locale) {\n        this.locale = locale;\n    }\n    DatePipe_1 = DatePipe;\n

The goal is to allow users to avoid the\n  most obvious pitfalls and do so without compromising performance significantly.\n  For ShadowDOM styling that's not covered here, a set of best practices\n  can be provided that should allow users to accomplish more complex styling.\n\n  The following is a list of specific ShadowDOM styling features and a brief\n  discussion of the approach used to shim.\n\n  Shimmed features:\n\n  * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host\n  element using the :host rule. To shim this feature, the :host styles are\n  reformatted and prefixed with a given scope name and promoted to a\n  document level stylesheet.\n  For example, given a scope name of .foo, a rule like this:\n\n    :host {\n        background: red;\n      }\n    }\n\n  becomes:\n\n    .foo {\n      background: red;\n    }\n\n  * encapsulation: Styles defined within ShadowDOM, apply only to\n  dom inside the ShadowDOM. Polymer uses one of two techniques to implement\n  this feature.\n\n  By default, rules are prefixed with the host element tag name\n  as a descendant selector. This ensures styling does not leak out of the 'top'\n  of the element's ShadowDOM. For example,\n\n  div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n  x-foo div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n\n  Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then\n  selectors are scoped by adding an attribute selector suffix to each\n  simple selector that contains the host element tag name. Each element\n  in the element's ShadowDOM template is also given the scope attribute.\n  Thus, these rules match only elements that have the scope attribute.\n  For example, given a scope name of x-foo, a rule like this:\n\n    div {\n      font-weight: bold;\n    }\n\n  becomes:\n\n    div[x-foo] {\n      font-weight: bold;\n    }\n\n  Note that elements that are dynamically added to a scope must have the scope\n  selector added to them manually.\n\n  * upper/lower bound encapsulation: Styles which are defined outside a\n  shadowRoot should not cross the ShadowDOM boundary and should not apply\n  inside a shadowRoot.\n\n  This styling behavior is not emulated. Some possible ways to do this that\n  were rejected due to complexity and/or performance concerns include: (1) reset\n  every possible property for every possible selector for a given scope name;\n  (2) re-implement css in javascript.\n\n  As an alternative, users should make sure to use selectors\n  specific to the scope in which they are working.\n\n  * ::distributed: This behavior is not emulated. It's often not necessary\n  to style the contents of a specific insertion point and instead, descendants\n  of the host element can be styled selectively. Users can also create an\n  extra node around an insertion point and style that node's contents\n  via descendent selectors. For example, with a shadowRoot like this:\n\n    <style>\n      ::content(div) {\n        background: red;\n      }\n    </style>\n    <content></content>\n\n  could become:\n\n    <style>\n      / *@polyfill .content-container div * /\n      ::content(div) {\n        background: red;\n      }\n    </style>\n    <div class=\"content-container\">\n      <content></content>\n    </div>\n\n  Note the use of @polyfill in the comment above a ShadowDOM specific style\n  declaration. This is a directive to the styling shim to use the selector\n  in comments in lieu of the next selector when running under polyfill.\n*/\nvar ShadowCss = /** @class */ (function () {\n    function ShadowCss() {\n        this.strictStyling = true;\n    }\n    /*\n    * Shim some cssText with the given selector.

The `element_inheritance` and properties are joined\n * using `element_inheritance|properties` syntax.\n *\n * ## Element Inheritance\n *\n * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.\n * Here the individual elements are separated by `,` (commas). Every element in the list\n * has identical properties.\n *\n * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is\n * specified then `\"\"` (blank) element is assumed.\n *\n * NOTE: The blank element inherits from root `[Element]` element, the super element of all\n * elements.\n *\n * NOTE an element prefix such as `:svg:` has no special meaning to the schema.\n *\n * ## Properties\n *\n * Each element has a set of properties separated by `,` (commas). Each property can be prefixed\n * by a special character designating its type:\n *\n * - (no prefix): property is a string.\n * - `*`: property represents an event.\n * - `!`: property is a boolean.\n * - `#`: property is a number.\n * - `%`: property is an object.\n *\n * ## Query\n *\n * The class creates an internal squas representation which allows to easily answer the query of\n * if a given property exist on a given element.\n *\n * NOTE: We don't yet support querying for types or events.\n * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,\n *       see dom_element_schema_registry_spec.ts\n */\n// =================================================================================================\n// =================================================================================================\n// =========== S T O P   -  S T O P   -  S T O P   -  S T O P   -  S T O P   -  S T O P  ===========\n// =================================================================================================\n// =================================================================================================\n//\n//                       DO NOT EDIT THIS DOM SCHEMA WITHOUT A SECURITY REVIEW!\n//\n// Newly added properties must be security reviewed and assigned an appropriate SecurityContext in\n// dom_security_schema.ts.

ngAfterViewInit lifecycle hooks (depending on the node\n// flags in lifecycle). Unlike ngDoCheck, ngOnChanges and ngOnInit, which are\n// called during a pre-order traversal of the view tree (that is calling the\n// parent hooks before the child hooks) these events are sent in using a\n// post-order traversal of the tree (children before parents). This changes the\n// meaning of initIndex in the view state. For ngOnInit, initIndex tracks the\n// expected nodeIndex which a ngOnInit should be called. When sending\n// ngAfterContentInit and ngAfterViewInit it is the expected count of\n// ngAfterContentInit or ngAfterViewInit methods that have been called. This\n// ensure that despite being called recursively or after picking up after an\n// exception, the ngAfterContentInit or ngAfterViewInit will be called on the\n// correct nodes. Consider for example, the following (where E is an element\n// and D is a directive)\n//  Tree:       pre-order index  post-order index\n//    E1        0                6\n//      E2      1                1\n//       D3     2                0\n//      E4      3                5\n//       E5     4                4\n//        E6    5                2\n//        E7    6                3\n// As can be seen, the post-order index has an unclear relationship to the\n// pre-order index (postOrderIndex === preOrderIndex - parentCount +\n// childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit\n// are stable (will be the same for the same view regardless of exceptions or\n// recursion) we just need to count them which will roughly correspond to the\n// post-order index (it skips elements and directives that do not have\n// lifecycle hooks).\n//\n// For example, if an exception is raised in the E6.onAfterViewInit() the\n// initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to\n// initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will\n// not have their ngAfterViewInit() called but, starting with E7, the rest of\n// the view will begin getting ngAfterViewInit() called until a check and\n// pass is complete.\n//\n// This algorthim also handles recursion. Consider if E4's ngAfterViewInit()\n// indirectly calls E1's ChangeDetectorRef.detectChanges().

It's possible for the identities of items\n * to change while the data does not. This can happen, for example, if the items are produced\n * from an RPC to the server, and that RPC is re-run. Even if the data hasn't changed, the\n * second response will produce objects with different identities.\n *\n * To customize the default option comparison algorithm, `<select>` supports `compareWith` input.\n * `compareWith` takes a **function** which has two arguments: `option1` and `option2`.\n * If `compareWith` is given, Angular selects option by the return value of the function.\n *\n * ```ts\n * const selectedCountriesControl = new FormControl();\n * ```\n *\n * ```\n * <select [compareWith]=\"compareFn\"  [formControl]=\"selectedCountriesControl\">\n *     <option *ngFor=\"let country of countries\" [ngValue]=\"country\">\n *         {{country.name}}\n *     </option>\n * </select>\n *\n * compareFn(c1: Country, c2: Country): boolean {\n *     return c1 && c2 ? c1.id === c2.id : c1 === c2;\n * }\n * ```\n *\n * **Note:** We listen to the 'change' event because 'input' events aren't fired\n * for selects in Firefox and IE:\n * https://bugzilla.mozilla.org/show_bug.cgi?id=1024350\n * https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/4660045/\n *\n * @ngModule ReactiveFormsModule\n * @ngModule FormsModule\n * @publicApi\n */\nvar SelectControlValueAccessor = /** @class */ (function () {\n    function SelectControlValueAccessor(_renderer, _elementRef) {\n        this._renderer = _renderer;\n        this._elementRef = _elementRef;\n        /** @internal */\n        this._optionMap = new Map();\n        /** @internal */\n        this._idCounter = 0;\n        /**\n         * @description\n         * The registered callback function called when a change event occurs on the input element.\n         */\n        this.onChange = function (_) { };\n        /**\n         * @description\n         * The registered callback function called when a blur event occurs on the input element.\n         */\n        this.onTouched = function () { };\n        this._compareWith = ɵlooseIdentical;\n    }\n    Object.defineProperty(SelectControlValueAccessor.prototype, \"compareWith\", {\n        /**\n         * @description\n         * Tracks the option comparison algorithm for tracking identities when\n         * checking for changes.\n         */\n        set: function (fn) {\n            if (typeof fn !== 'function') {\n                throw new Error(\"compareWith must be a function, but received \" + JSON.stringify(fn));\n            }\n            this._compareWith = fn;\n        },\n        enumerable: true,\n        configurable: true\n    });\n    /**\n     * Sets the \"value\" property on the input element.

For example, if one of\n * the controls in a `FormArray` is invalid, the entire array becomes invalid.\n *\n * `FormArray` is one of the three fundamental building blocks used to define forms in Angular,\n * along with `FormControl` and `FormGroup`.\n *\n * @usageNotes\n *\n * ### Create an array of form controls\n *\n * ```\n * const arr = new FormArray([\n *   new FormControl('Nancy', Validators.minLength(2)),\n *   new FormControl('Drew'),\n * ]);\n *\n * console.log(arr.value);   // ['Nancy', 'Drew']\n * console.log(arr.status);  // 'VALID'\n * ```\n *\n * ### Create a form array with array-level validators\n *\n * You include array-level validators and async validators. These come in handy\n * when you want to perform validation that considers the value of more than one child\n * control.\n *\n * The two types of validators are passed in separately as the second and third arg\n * respectively, or together as part of an options object.\n *\n * ```\n * const arr = new FormArray([\n *   new FormControl('Nancy'),\n *   new FormControl('Drew')\n * ], {validators: myValidator, asyncValidators: myAsyncValidator});\n * ```\n *\n  * ### Set the updateOn property for all controls in a form array\n *\n * The options object is used to set a default value for each child\n * control's `updateOn` property.

These methods ensure the controls are properly tracked in the\n * form's hierarchy.

Then you can pass it where it needs to go on submit.\n *\n * If you do need to populate initial values into your form, using a one-way binding for\n * `ngModel` tends to be sufficient as long as you use the exported form's value rather\n * than the domain model's value on submit.\n *\n * Take a look at an example of using `ngModel` within a form:\n *\n * {@example forms/ts/simpleForm/simple_form_example.ts region='Component'}\n *\n * To see `ngModel` examples with different form control types, see:\n *\n * * Radio buttons: `RadioControlValueAccessor`\n * * Selects: `SelectControlValueAccessor`\n *\n * @ngModule FormsModule\n * @publicApi\n */\nvar NgModel = /** @class */ (function (_super) {\n    __extends(NgModel, _super);\n    function NgModel(parent, validators, asyncValidators, valueAccessors) {\n        var _this = _super.call(this) || this;\n        _this.control = new FormControl();\n        /** @internal */\n        _this._registered = false;\n        _this.update = new EventEmitter();\n        _this._parent = parent;\n        _this._rawValidators = validators || [];\n        _this._rawAsyncValidators = asyncValidators || [];\n        _this.valueAccessor = selectValueAccessor(_this, valueAccessors);\n        return _this;\n    }\n    NgModel.prototype.ngOnChanges = function (changes) {\n        this._checkForErrors();\n        if (!this._registered)\n            this._setUpControl();\n        if ('isDisabled' in changes) {\n            this._updateDisabled(changes);\n        }\n        if (isPropertyUpdated(changes, this.viewModel)) {\n            this._updateValue(this.model);\n            this.viewModel = this.model;\n        }\n    };\n    NgModel.prototype.ngOnDestroy = function () { this.formDirective && this.formDirective.removeControl(this); };\n    Object.defineProperty(NgModel.prototype, \"path\", {\n        get: function () {\n            return this._parent ?

First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <input [formControl]=\"control\">\n * ```\n *\n * ```ts\n * this.control.setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n * @ngModule ReactiveFormsModule\n * @publicApi\n */\nvar FormControlDirective = /** @class */ (function (_super) {\n    __extends(FormControlDirective, _super);\n    function FormControlDirective(validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this = _super.call(this) || this;\n        _this._ngModelWarningConfig = _ngModelWarningConfig;\n        /** @deprecated as of v6 */\n        _this.update = new EventEmitter();\n        /**\n         * @description\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular `FormControlDirective` instance.

First, developers have found this pattern\n * confusing. It seems like the actual `ngModel` directive is being used, but in fact it's\n * an input/output property named `ngModel` on the reactive form directive that simply\n * approximates (some of) its behavior. Specifically, it allows getting/setting the value\n * and intercepting value events. However, some of `ngModel`'s other features - like\n * delaying updates with`ngModelOptions` or exporting the directive - simply don't work,\n * which has understandably caused some confusion.\n *\n * In addition, this pattern mixes template-driven and reactive forms strategies, which\n * we generally don't recommend because it doesn't take advantage of the full benefits of\n * either strategy. Setting the value in the template violates the template-agnostic\n * principles behind reactive forms, whereas adding a `FormControl`/`FormGroup` layer in\n * the class removes the convenience of defining forms in the template.\n *\n * To update your code before v7, you'll want to decide whether to stick with reactive form\n * directives (and get/set values using reactive forms patterns) or switch over to\n * template-driven directives.\n *\n * After (choice 1 - use reactive forms):\n *\n * ```html\n * <form [formGroup]=\"form\">\n *   <input formControlName=\"first\">\n * </form>\n * ```\n *\n * ```ts\n * this.form.get('first').setValue('some value');\n * ```\n *\n * After (choice 2 - use template-driven forms):\n *\n * ```html\n * <input [(ngModel)]=\"value\">\n * ```\n *\n * ```ts\n * this.value = 'some value';\n * ```\n *\n * By default, when you use this pattern, you will see a deprecation warning once in dev\n * mode. You can choose to silence this warning by providing a config for\n * `ReactiveFormsModule` at import time:\n *\n * ```ts\n * imports: [\n *   ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});\n * ]\n * ```\n *\n * Alternatively, you can choose to surface a separate warning for each instance of this\n * pattern with a config value of `\"always\"`. This may help to track down where in the code\n * the pattern is being used as the code is being updated.\n *\n * @ngModule ReactiveFormsModule\n * @publicApi\n */\nvar FormControlName = /** @class */ (function (_super) {\n    __extends(FormControlName, _super);\n    function FormControlName(parent, validators, asyncValidators, valueAccessors, _ngModelWarningConfig) {\n        var _this = _super.call(this) || this;\n        _this._ngModelWarningConfig = _ngModelWarningConfig;\n        _this._added = false;\n        /** @deprecated as of v6 */\n        _this.update = new EventEmitter();\n        /**\n         * @description\n         * Instance property used to track whether an ngModel warning has been sent out for this\n         * particular FormControlName instance.
