Arguments of method that called some other method.

[nthx]

Hi.

Is there any way to get underlined arguments:

public void method(Object _arg1_, String _arg2_)
{
 collection.add(arg2); <- join point "call(* $instanceof{java.util.Collection}>add(..))"

}

public Object advice(MethodCalledByMethodInvocation invocation)
{
 invocation.getArguments()[0] == arg2;
 invocation.getTargetObject() == collection;
 invocation.getCallingMethod() == method;

 ??? = _arg1_;
}

Thanks..
Tomasz

you cannot get arg1 as it is higher in the stack.

Thanks for quick answer.

But you could create in interceptor to intercept method(), and store the parameters somewhere, and then access that from your other advice.

To make a tunnel you say. Thanks for it. It could be done, but this place of storing.. it smells bad for me. I'll consider both. For now I put my joinpoint little higher to 'method()' and it will work for me, even though it breaks consistency of my solution... :(

It was just a thought... It could be very messy - I agree.
Some combination of ThreadLocal's and cflow might help a bit
