Using AOP to add new methods to a class/interface

[GiladHa]

Hello,

Can AspectWerkz/any other AOP framework, be used to weave
new methods to an existing class/interface?

An example:
I have a class
class Worker implements IWork {
public void doWork(A a, B b, C c)
{
do something ....
}
}

which implements an interface:
interface IWork {
void doWork(A a, B b, C c);
}


Can I write an aspect which defines, for both interface and
class, a new method called mock_doWork, which
receives the same parameters.

class Worker implements IWork {
public void doWork(A a, B b, C c)
{ ....
}

public void mock_doWork(A a, B b, C c)
{ ....
}
}

and:
interface IWork {
void doWork(A a, B b, C c);
void mock_doWork(A a, B b, C c);
}



Thanks for your assistance,

Gilad Haimov

Hmm. Looks simple. Didn't try it.
