Re: [aspectj-users] pointcut to match inherited methods

[Ashank <k_arvind_shankar@xxxxxxxxx>]

Hello Mohan,

You are right about using the 'call' pointcut and my guess is, if 'call' is
used, one would not need the 'withincode' part. However, as advised in
AspectJ docs, it is better to have a 'within' pointcut as it will be faster
and have a smaller footprint than just a 'call' pointcut, especially in
scenarios like load time weaving.

So I always preferred a combination of 'within' and 'execution' pointcuts to
match my method calls but I can't seem to use them for inherited methods for
some reason. 

Any ideas/thoughts?

Thanks
-Arvind
