Re: [aspectj-users] Help with defining pointcut for method execution on interface hierarchy

I'm quite new in Aspects, but I had to build an aspect for a similar isue.

execution(public A.*(..) ) worked for me.

Methods are in B, but in fact their main interface is A.
What do you all think?

Hi,

I solved it using a similar approach that you suggested but I was curious if you could construct it with a pointcut instead.  Thanks for your answer and for a great project!

I'm afraid I can't come up with a pointcut for that.  Best I could do
is something like:

aspect X {
       public static boolean check(JoinPoint.StaticPart jpsp) {
               Object o = ((MethodSignature)jpsp.getSignature()).getDeclaringType();
               boolean b = // work out what you want...
               return b;
       }
       before(): execution(* A+.*(..)) && if(check(thisJoinPointStaticPart))  {
               System.out.println(thisJoinPoint);
       }

}

where you do your extra analysis in the check() method.  But this is
not a purely static match of course.
