RE: [aspectj-users] Aspect Weaver

[Mariano Ceccato <ceccato@xxxxxx>]

Just a couple of question for the user community?

1) If AspectJ compiler can perform weaving at byte code level, does it means 
that I can modify standard java classes data structure using introductions on 
them and alter their behavior by using advices on pointcuts that intercept 
their methods? For instance lets consider the classes java.lang.String and 
java.util.HashMap.

2) I have a jar file containing some classes and I design an aspect that 
defines pointcuts that intercepts such classes. When I weave all together I 
modify the byte code inside the jar file. Is there a way to unweave my aspect 
from the jar file and get the original package even if I have no source code 
for that?
