Re: [aspectj-users] AspectJ wiki pages (was: Best practices in optimiza

Thanks for kicking this off Simone.  I'll comment when I can and maybe
once I get the timers in place properly we can include a suitable
diagnostic section related to them.

To answer some of Bepis questions:

>> I haven't understood if the include clause in aop.xml have influence

Support for aop.xml configuration in the IDE (eclipse) for compilation
is in the very early stages.  It is more for helping you get your
aop.xml right rather than trying to make weaving faster.  The include
clause in there will currently not be respected for ITDs, but only for
advice (as this is a work in progress).  But really an include clause
is just another way to write a within() pointcut.

that is what I would expect

I don't believe it implements fastMatch - but I think it probably
could.  I'd imagine withincode making a difference if you are matching
a lot of call joinpoints.

What you see is a message that says "woven X" - this means it has been
through the weaver, it does not mean the type was changed at all.  I
really should change that message as it gives the wrong impression.  A
suitable within() clause will have caused the weaver to return
immediately and not change the type.  Whether it actually got modified
is reflected in weave info messages and the advice markers you see
after compilation.

Always try to include a scoping pointcut if possible, they are cheaper
to evaluate even thought they don't all implement fast match (yet).
