Re: [aspectj-users] Final Classes

[Paulo Alexandre Corigo Zenida <paulo.zenida@xxxxxxxx>]

Ron,

	I suppose I didn't explain myself quite well. You are absolutely right about 
what you've just said. Actually, what I was trying to do is something else: 
I'm trying to capture the class itself being final, not its constructor being 
final. The source code I have put here was just to simplify but I guess it 
wasn't well chosen. I would like to do something like the following:

// The following does not compile
pointcut finalClasses() : call(* (final *.*)(..)) 
&& !within(DetectFinalClassesAspect);

Is there a way to see if a class is declared as final?

Best regards,

	Paulo Zenida
