| You can't bind the JoinPoint available in advice this way.
|

Why not? I think I have even read about this in one of AJ book (Cookbook?).

| Valerio, do you instead want to log the join points being
| advised by the advice (in Main below, staticinitialization
| and method-execution)?  If the pointcuts were named and

| the use-case for this? Does the variable
| thisEnclosingJoinPointStaticPart help?

| | i don't need to refine it. It'd be enough to be able to "dump" the
| stack
| | everytime an advice is executed.
| |
| | i tried with :
| |
| | pointcut Advices(): adviceexecution() && within(TraceAspect);
| |
| |     after(): Advices() {
| |           StackTraceElement ste = new StackTraceElement
| | (thisJoinPoint.getSignature().getDeclaringType().getName(),
| |                 thisJoinPoint.getSignature().getName(),
| |                 thisJoinPoint.getSourceLocation().getFileName(),
| |                 thisJoinPoint.getSourceLocation().getLine());
| |          System.out.println("BeforeAndAfter advice: "+ ste);
| | }
| |
| | so, if another advice is present, i want to get info about that join
| point.
| | This is not possible? If so...why ?
| |
| | thanks,
| | valerio
|
| I think what you are looking for is something in this direction:
|
| pointcut advices(JoinPoint jp): adviceexecution() && args(jp) &&
| within(...)
