[aspectj-users] Re: Why is 'if' pointcut restricted to static members of

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

An "if()" poincut can only make references to static fields and methods
because it executes outside the context of an aspect instance. However you
can always use the "aspectOf()" method:

public aspect Aspect {

      pointcut testIf () :
            execution(* main(..)) && if(Aspect.aspectOf().isEnabled());

      before () : testIf () {
            System.err.println(thisJoinPointStaticPart);
      }

      private boolean enabled = true;

      public boolean isEnabled () {
            return enabled;
      }
}
