Tracking an object

[oberon777]

Is there a simple way to track all method calls on a particular object?

For example, suppose I am interested what happens to objects that are returned as the result of Class.forName(..) and I want to record all method calls happening on them.

I suppose tracking ALL calls is easy, but how do I make it so that the constraint that the object in question is the return result of Class.forName(..) is part of the pointcut expression. Thanks.

That is not possible, pointcuts are static.

However, you can intercept calls to Class.forName(), and use the dynamic per-instance api to add interceptors to the returned object. For this to work though, the returned objects need to have been prepared.
