Addition to OW2 ASM library to support generating descriptors and signatures from TypeMirrors/Elements.
The ASM library has classes that can process Java class files through a Visitor style API allowing users to examine or modify any part of a class. The ASM Mirror project adds comparable classes to do the same with TypeMirror and Element instances used during Annotation Processing.
| ASM Class | ASM Mirror Class | Description |
|---|---|---|
| ClassReader | MirrorClassReader | A parser to make a ClassVisitor visit a TypeMirror/Element instance. |
| Type | MirrorType | A Java field or method type. |
The Java spec requires "signatures" for generic descriptors. The ASM library has some internal utilities for generating these.
The ASM mirror library provides SignatureMirrorType to generate generic signatures from TypeMirrors/Elements.
Usage is the same as for the ASM library except you pass in a TypeMirror element from an annotation processor instead of a class file. ASM Mirror calls a standard ASM ClassVistor E.g.
MirrorClassReader reader = new MirrorClassReader(processingEnv, element);
reader.accept(myClassVisitor); // standard ASM ClassVisitor
