Thanks very much Fintan, I'm close to getting it working, but no cigar.
I think this is because the method I am targetting is inherited.
I have a class called CallForOfferServer which inherits the method
action() from a class called Behaviour as follows:
Behaviour
^
SimpleBehaviour
^
LifeCycle
^
CallForOfferServer
I am trying to advise the action() method only when it is called from the
class CallForOfferServer, but just can't nail it.
Any help would be great. This is my failing code:
*pointcut* callAction() : *call*(* jade.core.behaviours.Behaviour.action())
&& *target*(apoptotic.bookTrading.BookSellerAgent.CallForOfferServer);
*void* *around*( ): callAction()
{
\\ do something
}
Really appreciate your help
Thanks
Rob
