ARC Object Implementation

Class Real is to be implemented by the applications programmer. This class shown in Figure 4 implements interfaces IMyObject and ITrigger. Observe that figures 3 and 4 shows interface IMyObject as a subclass of interface IRefCount. Reference counting has been a common feature used in component programming with COM/DCOM models [6] to keep track of usage. This feature is useful for garbage collection, especially to take care of references that an object may accumulate while hopping from machine to machine. A library implementation of reference counting may be used in class Real through inheritance.
