RE: [aspectj-users] weave-only w/o aspectj runtime elements

["Ron Bodkin" <rbodkin@xxxxxxxxxxxxxx>]

Have you actually measured the overhead caused by this David? One thing to
consider is that an if(flag) pointcut can be evaluated inline to avoid even
the overhead of a method call in cases where you don't want to measure
performance.

I presume you mean the forwarding methods ajc$XXX that are invoked
from the woven code and that actually execute your desired behaviour.
No, those can't be removed.  We work hard to optimize what is inserted
but we have that layer of indirection to ease situations like separate
compilation.  Suppose you change the behaviour you want to be woven,
by using the indirection we only have to recompile the aspect - if
everything was inlined directly then we'd have to recompile/reweave
everything.
