Re: [aspectj-users] aspectj joinpoint *for* Annotation ?
|
Hi Henrique,
We tend to consider advice constructs as different to 'regular'
methods. For example:
before(): execution(* *(..)) {}
doesn't advise itself, or any other advices. The adviceexecution()
pointcut is for working with advice join points. Coming at it from
that angle, we are perhaps missing a construct like this:
declare @advice: before(..): @MyAnnotation;
But I haven't seen many use cases calling for it.
cheers
Andy
