Reply To: Selecting a subtype instance in OAL

[Dennis Tubbs]

I would be in favor of deferred (abstract) operations. Polymorphic events are a great way to delegate events to a subtype to handle, when the event is part of the subtype’s natural life-cycle. But it has always bothered me when I have to create a state model for a class that has nothing to do with the state behavior of the class. Why should a class have a state model if it does not have any interesting behavior?
