Re: [aspectj-users] Detect annotated method

["Wes Isberg" <wes@xxxxxxxxxxxxxx>]

Hi -

AJDT/ajc is pretty good at telling you where the problem is.
The syntax error is due to using the annotation for the method
name (illegal) not the method modifiers.  The signature pattern 
should look like a method declaration, which puts the modifiers
in front of everythihng.

err: call(* *.(@MyAnnotation *)(..))
 ok: call(@MethodAnnotation * *.*(..))
 ok: call(public !synchronized @MethodAnnotation * *.*(..))

To target a method with an annotated return type:
 ok: call((@ReturnAnnotation *) *.*(..))

To target a method declared on an annotated class:
 ok: call(* (@ReturnAnnotation *).*(..))

(except: is the latter working? was that a bug at one point?)

hope this helps - Wes
