// Description:+
−
// Together, these classes and the CBTPortProxy implement the +
−
// State pattern.  The states themselves are implemented using +
−
// the Flyweight pattern.  Each state is a Flyweight object+
−
// and CBTPortStateFactory is manager of these objects.  As a +
−
// result of being a flyweight, no state object may have a state +
−
// that can't be shared between all possible users of the state.+
