[aosd-discuss] excluding a joinpoint shadow

[Peter Kim]

Hi,

What is the best way to go about allowing a particular joinpoint
shadow (e.g. AST node) to be excluded from being advised?  For
example, if I have an aspect that advises call(* *.bar()), to exclude
calls to bar() within operation, I would modify the pointcut to "&&
!withincode(operation())".  However, I would like to allow the user to
exclude only the first call to bar() through some comment-annotation
mechanism as follows:

void operation()
{
   foo();
   bar();
   //@exclude
   bar();
}

I understand that this probably requires some modification to AspectJ
infastructure, but I'm not very familiar with the infrastructure and I
would like to know the fastest way to achieve this (though not too
dirty)...thank you so much!
