Re: [aspectj-users] Passing state between around advise

Speculation. Just give it a try. There are other workarounds, but clean code is also something IMHO. ;)

My concern with thread local is the cost of gets and puts.

I'm not sure If the per* solution will help as it would create a lot of garbage if aspect instances are generated at a high frequency.

I want to share contextual information between Around advice invocations for the same thread.  For example I'm interested in storing the signature from previous advice execution for the same thread so I can log caller method corresponding to the current callee.

I don't fully understand if the proceed API with arguments allows info to be exchanged between  subsequent advice calls or if its intent is to override the agreements passed to the point cut?

The other option potentially i would need to maintain a aspect instance per thread and could have a member that contained the previous signature.

Looking for suggestions on how to accomplish this.

Thanks.
