I was intending to do more research before I responded to any of the other emails, but haven't had a chance to do that.
Anyways, My requirement was, If I could have a custom JoinPoint that can do special translation for some specific method arguments in its current context. The reason being, In a FlightRecorder utility, if I were to cache the JoinPoint for dumping the data to a log file at a later time and one of the method arguments had a huge memory footprint, I wouldn't want to cache that particular argument and hold on to the reference, instead I would convert that parameter to a brief String in the JoinPoint and cache the JoinPoint. My Custom JoinPoint would detect such arguments and immediately convert them to a brief string and not cache the object argument ( Not sure what can of worms that this would open, but it should be doable right?) Now, may be there are other ways of doing this without derived/Custom JoinPoint, like the user object proposed in the bug for AspectJ https://bugs.eclipse.org/bugs/show_bug.cgi?id=89009. This would mean creation of 2 objects for logging ( one is the JoinPoint that would be created and other is the userObject to be set in the JoinPoint in addition to some reflection calls). I think the hit would be limited to creation of just 1 Object if the userObject was part of StaticJoinPoint ( which was also suggested in the bug comments). Or another idea that was brought up independent of AspectJ was using weak references which again is Object creation ( might end up doing this if nothing else works). Hope this discourse above is clear enough to explain my requirements.

I will also create a case for letting users create custom JoinPoints in AspectJ. Iam sure if Aspectwerkz allowed it and aspectbench allows it, there are already compelling usecases for having done that in these products. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Wes Sent: Wednesday, September 27, 2006 9:01 PM To: [email protected] Subject: Re: [aspectj-users] Custom JoinPoints AspectJ is open-source, so you can write and use a different implementation. aspectjrt.jar combines the runtime and aspectj5rt projects. Just make sure it's binary-compatible, and, for clarity's sake, rename the jar as your internal version - e.g., "aspectjrt-tencor-1.1.jar" If you want us to support new features, please submit a compelling bug/use-case.
