Serialization

Fiber separates serialization and the IR tree, allowing you to convert back and forth from practically any format. By default, fiber comes with Jankson, which is a JSON superset that allows comments.

Let's start off by creating a dummy IR:

@Settings(namingConvention = UnderscoredLowerCaseConvention.class)
private static class MyConfiguration {
    private int fooBar = 5;

    @Setting.Node
    private SubNode node = new SubNode();

    public static class SubNode {
        private String bazQux = "Hello world!";
    }
}

ConfigNode node = new ConfigNode();
AnnotatedSettings.applyToNode(node, new MyConfiguration());

To serialize this IR into a Jankson file, create a JanksonSerializer:

JanksonSerializer serializer = new JanksonSerializer();

And just call the serialize method.

serializer.serialize(node, System.out); // note: we're writing to sysout, but this could be a FileOutputStream

This will produce the following output:

{
	"foo_bar": 5,
	"node": {
		"bazQux": "Hello world!"
	}
}
