Hello, I'm a c++ programmer and I have a qestion about a simple code
implementation in Java.

Basicly, I have a set of EventHandlers (just some class). Handlers
could be added/removed/suspended/active...
EventHandler is a class written by someone else and it must not be
modified; this class knows nothing about suspended/active state.

The way I'd do this in c++: make a set of std::pair<EventHandler,
State> or something like this.

here's how I did this in Java and it doesn't work.
class EventHandlerWrapper extends EventHandler {
   public enum State {
       SUSPENDED,
       ACTIVE
   }
   protected State _state = State.ACTIVE;
   public void Suspend(){
       _state = State.SUSPENDED;
   }
   public void Resume(){
       _state = State.ACTIVE;
   }
}

Now I want to be able to add EventHandler's into the
Set<EventHandlerWrapper>, but it doesn't work. I' messed up with
casting etc.

what's the right way to do this kind of stuff in Java

thanks!!
