RE: [aspectj-users] Detect annotated method
|
Hi again,
First of all, you are welcome. Anyway, I have also made a mistake (I
have switched the methods names - m() and n())
The previous will match against the m() method and not the n() one,
right?
What I wanted to say is:
The previous will match against the n() method and not the m() one, right?
Thanks for clarifying what you really wanted :)
Still, have you tried the following? (it should work...)
Object around() : call(* *.*(..)) && !call(@MyAnnotation * *.*(..)) .... ?
Cheers,
Paulo Zenida

Sorry, I tryied to make things simpler but I just made it more
confusing. In the end, my words said one thing and my code said
another.
What I really wanted to do was to avoid having the aspect applied to
methods that are annotated by MyAnnotation. So that programmers could
specify which methods are exceptions regarding the application of the
aspect I'm creating.
But I did not wanted to explain all this to the mailing list users,
since it's a very specific detail about my project.
Anyway, thank you very much for your contribution. Now my code is
clean and functional.

Hello,
Let me see if I understand this...
You want to capture this
@MyAnnotation public void m() { ... }
and not this
public void n() { ... }
then, why are you trying this
Object around(): call(* *.*(..)) && !call(* *.(@MyAnnotation *)(..)) or this
Object around(): call(* *.*(..)) && !@annotation(MyAnnotation) ?
The previous will match against the m() method and not the n() one,
right? Anyway, have you tried something like:
Object around() : call(* *.*(..)) && !call(@MyAnnotation * *.*(..)) .... ?
Best regards,

Hi -
Glad you found a way to do it; sorry you had to do it the hard way!
AspectJ 5 features are discussed outside the programming guide
(which will be fixed soon at least with forward references):
http://www.eclipse.org/aspectj/doc/released/adk15notebook/index.html
This section discusses signature patterns:
http://www.eclipse.org/aspectj/doc/released/adk15notebook/annotations-pointcuts-and-advice.html#signaturePatterns
It says that the annotation must be first in any modifier list.
(In Java annotations can be anywhere in the modifier list,
though they recommend the annotations come first as a matter of style.)

I just found a way to do it:
Object around(): call(* *.*(..)) && !@annotation(MyAnnotation) &&
etc....
sorry for this.
I was too stuck to the Programming Guide
(http://www.eclipse.org/aspectj/doc/released/progguide/index.html) and
could not find references to annotation style matching.
Anyway, is there any more comprehensive reference than the programming
guide?
