Actually, you already did this. The problem is just that AJDT don't have the
ability to show the match of cflow correctly. As Eric said, cflow need to be
determined dynamically during the run-time, but AJDT cannot predict exactly
what happens in the run time, so it marks all possible points which are
possible in the cflow of the pointcut, which may confuse you.
Try run the following code, you will see you did right and AJDT did wrong.
package controlFlowPointcutsExamples;
public class Test {
static void add() {
}
public static void main(String[] args) {
System.out.println("before foo");
foo();
System.out.println("after foo");
}
static void foo() {
System.out.println("execution foo");
add();
}
}
package controlFlowPointcutsExamples;
public aspect TestAspect {
pointcut fooPC() : execution(void
controlFlowPointcutsExamples.Test.foo());
before() :
cflow(fooPC())
&& !within(TestAspect)
{
System.out.println("before cflow execution(void
controlFlowPointcutsExamples.Test.foo()). JoinPoint: " + thisJoinPoint);
}
}

Subject: Re: [aspectj-users] Problems with cflow in eclipse
So what can i do to correct that so that it doesn't match anywhere? I want
that pointcut to match anything that is in the control flow of foo().
