RE: [aspectj-users] AW: Pointcut on a constructor with a custom@Annotati

["Ron Bodkin" <rbodkin@xxxxxxxxxxxxxx>]

Hi Moritz,

Please take a look at this FAQ entry:
http://www.eclipse.org/aspectj/doc/released/faq.html#q:adviseconstructors 

Basically, you can't use @target for the call to a constructor: there isn't
one. You could use @target for execution of the constructor or you could
bind the returned object with after returning advice and then use reflection
to test for an annotation on the object.

Subject: [aspectj-users] AW: Pointcut on a constructor with a
custom@Annotation

Hallo Again

Sorry, I hit send accidentally. :(

So I continue here with the mentioned pointcut:

@AfterReturning(pointcut = "call(* .new(..)) && @target(MyAnnotation)",
returning = "obj")
  public void objectCreation() {
  }
 
The problem here is, that the combination of the call(* .new(..)) and the
@target(MyAnnotation) does not work. I can either remove the @target and it
works fine or I can remove the call(..) and let the @target be the key. But
together those two do not work.

Am I doing something completely wrong? Or is there another suggested way to
intercept a newly created object?

Any help is appreciated

Regards
Moritz Post
