Remarks
This class uses an indirect mechanism for implementing parameter properties. Each property get method calls a virtual protected method that retrieves the property. Each property set method, on the other hand, calls three virtual protected methods: one indicating that the property is changing, another actually changing the property, and a third indicating that the property has changed.
This allows the property setter to isolate the handling of invalid input in the property changing method, set the property, and apply any side effects in the property changed method. This also allows the base class to provide some default error checking to match the semantics defined by the parameter interface.
