Re: [aspectj-users] Trying to find pointcut for direction recursive meth

[steenreem <steen.reem@xxxxxxxxx>]

Thanks Simone! That helps.

The pointcut works now. So I could for example print a message each time the
pointcut is reached. But what I really want it not to insert any advice at
the pointcut. I just want to loop over all the pointcuts and store the name
of the method that is called.
