Hi
What about using an annotation processor? It should give you what you
need (the ability of inspecting fields, methods classes declared by a
class).
Some basic documentation about annotation processing:
http://java.sun.com/javase/6/docs/api/javax/annotation/processing/Processor.html#getSupportedAnnotationTypes()
Note: if you make your processor's getSupportedAnnotationTypes to return
'*', that should allow you to process every element in a source file,
even those without annotations.
