Explicit tests for inner, member, and anonymous classes

I have built up a simple GUI builder tool that I use to experiment with different layout managers and general coding exercises. Now I'm playing with a simple ( or maybe it will become not so simple) code generator that will unwrap the root container and spew out source code that can be compiled to recreate the UI structure.

Well, I guess I've gone brain dead because for the life of me, I can not recall ever explicitly testing a class to determine if its an inner class, anonymous class, component member class, etc.

With the .getClass().getName() its easy to screen out the anonymous classes with a test for the '$' delimiter, but the question becomes "Is there a more formal test that can be applied?" such as using ancestry. Would appreciate anyone's experiences in unwrapping and code generation.

If I ever get it unscrewed to the point I'm not embrassed by the code I'll post it back here for the next person's query. Thanks All,

If you use JDK 5, there are a number of new methods in the Class class which can help you - isAnonymousClass(), isMemberClass(), getContainingClass(), etc. For earlier JDKs - well, there's getDeclaringClass() at least. That can be used to tell you if you're dealing with a member class, though it's no good for identifying local or anonymous classes. What you're trying to do will be much easier under JDK 5, that's for sure.
