I have run into a problem where one of the helper classes invoked by one of my
advices triggers a joinpoint which causes an infinite loop to occur. I would
like to prevent this from happening by modifying my initial poincut to not
match any subsequent pointcuts that get triggered as a result. Effectively I
would like to have a join point that says, "turn off any other joinpoints until
after the current advice has finished executing".
From what I have been reading, cflowbelow serves this very purpose. However I
have had no luck. This is generally what my aspect looks like:
public aspect MyAspect {
pointcut myPointCutA() : within( my.package..*) &&
execution(*
my.package..*.someMethod*(..)) &&
!within(my.package.MyAspect);
pointcut subsequentPointCutAs() : cflowbelow( myPointCutA() );
Object around() : myPointCutA() && !subsequentPointCutAs() {
// calls to other classes which call other classes which may trigger
pointcut again
}
}
From my tests, I see that the subsequent poincuts are still being triggered.
Have I completely misunderstood how cflowbelow functions? If cflowbelow is not
meant to be used this way, what approach would you recommend I use?
Thanks!
