I think if we are going to do this, we should be able to classify the pointcuts fully. The expression tree from javacc when we parse a Pointcut from the string representation already contains the full structure, so I guess it is just a case of creating another visitor to classify the pointcut when we add the pointcut to the AM. We should split the "execution" classification into whether a method or constructor is called as well.

Sounds like a good idea, although we need to keep the existing API since we have gone CR. The old methods could just wrap the new structures.

If we add a new binding containing an execution pointcut for methods, then as a result of that the affected advisors should only rebuild their method chains, no point in rebuilding constructors, fields etc.

On that note, if adding a field read/write pointcut, we should ignore all Advisors that cannot have advised fields, such as the ClassContainer and ClassProxyContainer.
