ABSTRACT:
A system allows a non-virtual method of a base class inherited by a derived class to be effectively overridden so that code developed to access the method via the base class accesses the overriding behavior. The system replaces an instance of the derived class with a dynamic object and transparent object with the transparent object appearing to provide to invoking code an implementation of the derived class. Upon receiving an invocation of a method, the transparent proxy directs the invocation to the dynamic object by invoking an invoke method of the dynamic object passing an indication of the invoked method of the transparent object. The dynamic object may be an instance of a dynamic class that inherits a real class with a virtual invoke method. The dynamic class overrides the invoke method to provide overriding behavior.
