Hi Rob,
Instead of a "before" advice, use an "around" advice. With an around
advice you need to call the method proceed() to run the original method.
Thus in your advice if the security test allows the method to proceed
you call the proceed() keyword, otherwise skip.
Regards,
Fintan

Subject: [aspectj-users] Removing functionality with AspectJ?
Hi there,
I'm completely new to AspectJ and was wondering if there is
anyway to cause a method to be "skipped" with AspectJ.
Apologies if the question sounds silly, but I am using AspectJ
to monitor what is going on in an object for security purposes.
If certain conditions have been met, a rule engine implemented
in a before advice determines that the code in that method should be
skipped. Naturally, for this to be in anyway feasible, the method in
question would need not to return anything, something like
public
void action()
I guess I need something like a decorator pattern that removes
functionality rather than adds it. The only way I can currently think do
to this is to use my aspect to change the value of a boolean variable in
the target method which causes the code to exit without doing anything.
Really appreciate your help
Thanks
Rob
