Re: [aspectj-users] Binding pointcut arguments to static values

[Andy Clement <andrew.clement@xxxxxxxxx>]

I don't think you can express that in quite the way you wish, but this
would work in the case you have:

    pointcut foo() : call(public void HelloWorld.foo());
    pointcut bar() : call(public void HelloWorld.bar());

    pointcut interesting() : foo() || bar();
    before() : interesting() {
        String name =(( CodeSignature)
thisJoinPoint.getSignature()).getMethod().getName();
        String typename =(( CodeSignature)
thisJoinPoint.getSignature()).getMethod().getDeclaringClass().getName();
        System.out.println("Going to call method " + name+ " on type
"+typename);
    }

If the data (FOO or BAR) were in an annotation attached to foo() or
bar() you might be able to get closer to your desired syntax, but that
doesn't seem a good solution.
