Hello,
I am trying to instrument classes at load time and I thought about using
WeavingAdaptor.
I use my own agent, to perform other types of analysis on the bytecode. Thus I
would like to use the load-time facilities offered by AspectJ out of their
normal context. I searched a bit and I found WeaverAdapter. However, what is
not clear to me is how to use it. Could someone point me to a tutorial,
example, etc?
I would like to ask what is the GeneratedClassHandler for? Also, do I need to
pass to the WeaverAdapter the entire classpath for the classes, since I already
have the bytes of the class I want to instrument?
Also, for the URLs for the aspects, do these have to point to an .aj file? or a
compiled version? I tried with the ".aj" files but no success.
This is the log of my actions:
