ABSTRACT:
A dynamic proxy object is disclosed that is capable of intercepting calls from a calling object to a target object. The dynamic proxy can imitate the target object so that even though the calling object may be of a different version or type from the target object, it can still communicate with the target object. Specifically, the dynamic proxy can intercept early bound invocation by the calling object, obtain metadata from these invocations, and pass it to an adapter via a set of reflective interfaces. The adapter can also obtain metadata from the target object via late bound invocations, and then compare this metadata to the metadata provided by the dynamic proxy in order to make a determination whether or not the calling object and the target object should be communicating. If so, communication can occur between the calling and target objects in spite of differing versioning or object types.
