AspectJ pointcut on method variable, is it possible?

I have been using AspectJ for a while and it works great on object scope fields containing annotations. I just ran into a situation where I want to annotate a variable of method scope that will work with my pointcut but I am having trouble with it.

Here is the pointcut that I am using. It works fine if my variable is a field for the object, but if I reduce the scope to a method (variable declared inside the method), then it doesn't work anymore and I am not sure why. Let me know what I can do, thanks.

 after(final Trigger trigger): set(@Triggereable * *) && args(trigger)
 {
  System.out.println("trigger flush");
 }

Also, here is an exmaple of what I want to work. That System.out.println above should fire when the Trigger is instantiated:

public void foo()
{
   @Triggereable
   private Trigger trigger = new Trigger();
}
Solution

  • AspectJ does not currently support pointcuts on local variables (read the FAQ entry).

    I seem to recall a recent discussion about such a feature possibly added soon, but I could not find it in the AspectJ issue tracker nor in the Mailing List archives
