Re: [aspectj-users] how to intercept joinpoints ...

["Fabio Fagundes Silveira" <ffs@xxxxxx>]

Hello,

   Hum, ok, but if you don't have the Aspect1 source-code, that is a little
bit difficult to implement ... Let's suppose you just have the  aspect and its
specification, where you can find out everything you need... :-) So you decide
to intercept its joinpoints as you have showed us. Is there any way to do this
as you can do it with a class when you dont have the source? I meant, if the
class documentation tell me that it has a "withdraw" method, it's easy to
write an aspect to intercept it, right?

thanks a lot
