What are the best ways to get "around" extending a final class? I want to
- add methods
- add class annotations
I think using a wrapper class could solve my issue, since the class doesn't have to be a subclass of my final class in this case. It just needs its functionality.
If I'm doing this, is there an easier way than copying all the public methods and passing them to the inner object?
