Re: [aspectj-users] Singling out one function in the intersection of cfl

Marc-Andre,

Yes. Try this:

public
aspect
Aspect {

        before
() : execution(void
third()) && cflow(execution(void
second())) && cflow(execution(void
first())) {
         
      System.out.println("Aspect.before()
" + thisJoinPoint);
        }
}

public
class
Test {

        public
void
first () {
         
      second();
        }
        
        public
void
second () {
         
      third();
        }
        
        public
void
third () {
         
      System.out.println("Test.third()");
        }
        
        public
static
void
main(String[] args) {
         
      new
Test().first();
         
      new
Test().second();
         
      new
Test().third();
        }

}

Aspect.before() execution(void test.Test.third())
Test.third()
Test.third()
Test.third()

Subject	[aspectj-users] Singling out one function in the intersection of        cflows

Hello,

I was wondering if I can extract a single function that would match cflow(a)
&& cflow(b).
My understanding is that they will 'return' sets of matching functions,
but I need to extract only one point
in order to create a generic solution.

Any ways I can do that?

Thx,

MA
