[aspectj-dev] Re: [NEWSDELIVER] Is there any usage like the following in AspectJ?
|
Here is an example for the second idea.
pointcut mypointcutA():
cflow(execution(A.method1()) && within(B))
pointcut mypointcutB():
execution(A.method1()) && if(mypointcutA.getSignature()!=null)
in mypointcutB, we take mypointcutA as a reference. this reference
has the same functionality as thisJoinPoint.

Zifu,
Your first idea sounds like "pcflow()" or predictive cflow:

. I'm not quite about your second idea. Can you elaborate?
BTW I have posted this t aspectj-dev which is a better place to discuss possible AspectJ enhancements.

Subject: [NEWSDELIVER] Is there any usage like the following in AspectJ?
pointcut mypointcut(): execution(A.method1()) && if
(exists(cflow(execution(A.method1()) && within(B)))
My question is about the "exists". Is there any way to know if some
pointcut exists or not when defining
the pointcut?
My intention is that I want to generate execution(
A.method1()) depending on
if cflow(execution(A.method1()) && within(B)) exists.
As we know, "thisJoinPoint" can give us some useful information.
But I really hope there is some usuage model for getting information from
any join point,not only for thisJoinPoint in an
advice block.
for example, mypointcut().getXXXXX().
