RE: [aspectj-dev] disabling aspects

["Oleg Lebedev" <oleglebedev@xxxxxxxxxxxxx>]

Never mind my last question. IAJC correctly generated the corresponding
aspect class. The problem was that my next "compile" target was
regenerating my class folder.

I need to use my regular "compile" task, because my JRE has JMF
extensions. How can I force iajc task to use JMF libraries from my JRE?

Thanks.

Oleg

Alexandre,

I tried using your approach, but I get a compiler error saying that
class A is not found when I try do A.aspectOf().toggle(). Is iajc Ant
task supposed to create this class for aspect A?

Thanks.

Hi

You can use an if pointcut and a boolean "isEnable" field in the aspect:
aspect A {
  boolean isEnable = false;
  toggle() {
    isEnable = !isEnable;
  }// write deploy / undeploy instead perhaps for clarity
  ... // advice / pointcut using if(isEnable)
}
Then you can use A.aspectOf().toggle() to turn it on and off.

You can use the very same patterns using @AspectJ syntax since if()
pointcut is supported there as well.

There has been a discussion at last AOSD about that. Perhaps someone has
the notes or a link to share.
