Andy -
Your solution is very elegant! I hadn't dealt with class collectors
before, I can see how they could be handy for something like this. The
code works perfect for an aspect such as this:
before() : execution(void edu.wm.test..*.run()) {
System.out.println("Wrap-C");
}
But if I try to wrap around a function call:
void around() : execution(void edu.wm.test..*.run()) {
System.out.println("Wrap-C PRE");
proceed();
System.out.println("Wrap-C POST");
}
I get the following output:
Wrap-C PRE

... 5 more
The aspect is obviously getting applied, the call is getting
intercepted, but I can't seem to proceed() back into the code. Is this
due to the Groovy class only existing within its own ClassLoader? But
wasn't that the case before?
Thanks again for your help!
