RE: [aspectj-users] "AspectJ question"

["Echlin Harmer, Elizabeth" <echline@xxxxxxx>]

You can order advice between different aspects by applying a precedence rule:

declare precedence: firstAspect, secondAspect.

For advice within an aspect, the ordering is the order the advice appears in the aspect. So for your case below, if you move the static affecting advice before the advice for all methods you will get them in order.

Hi All,

I´m working with AspectJ and recently get a Problem:

In order to ilustrate, consider the simple example:

public class C{

  public void m(int a, int b){ }

}

And an aspect like:

public aspect AspectoC {

     // Advice to run at beginning of every execution of method m()

      before(C current) :

            execution(void C.m(int ,int)) &&

            within(teste.C) &&

            this(current){

           

            System.out.println("Code executed (I want to run in SECOND, but it runs in FIRST!!) before any code of method m() in Class C executes");

      }

            // Advice to run a specific code at beginning of all methods non-static!

      before(C current) :

            execution(!static * C.*(..)) &&

            within(teste.C) &&

            this(current){

           

            System.out.println("This (I want to run in FIRST before everything) must execute before anything in methdo m() in Class C");

      }

}

The question is: Is there a possibility to execute the second advice always in FIRST?

 

 - The second advice is applicable to all methods in Class C, but a method m() is affected by the first advice. Thus, the first advice executes first than the second. I want a way to apply to all methods non-static to execute the second advice at FIRST. And if there is a method that has an advice that affected it, I would like that this advice executes after that the advice that affect all methods non-static.

 

IF I execute this code it returns this result:

Code executed (I want to run in SECOND, but it runs in FIRST!!) before any code of method m() in Class C executes

This (I want to run in FIRST before everything) must execute before anything in methdo m() in Class C

(So , I want a way to bring me a inverse result!!!)

Thanks to ALL!
