At the appropriate level, even the call to setChanged() is tautological since any method call changes the state of the program. Given the semantics of ConnectionFactory, however, I don't think the factory's state changes when it creates a connection. And yes, I may be overthinking it. | |

Think about your layers of abstraction - somewhere changed state. I wonder if a new connection is merely a component of a "higher perspective" state change; perhaps there is an abstraction that needs a more formal/concrete presence. Finally, mega-dittos on the observation of over-thinking pattern implementation and use. | |
