Abstract
Component Object Model (COM) defines two approaches: Containment and aggregation concentrating on the consumer perspectives for component reuse,which is not favorable to the self-evolution of component and separation of concerns. A new method for component reuse was proposed. First,a new component class was derived directly from an old component. The derived class reused base class's interfaces and events,overloaded virtual interface methods,and defined new interfaces and events. Second,identifiable features were as taken the well defined semantic entities,so that they could be bound to other component at compile or run time. The design and implementation methods on middleware platform were presented. The mobile telephone projects experiments show that the new method contributes to improving software development efficiency and increasing the quality of software systems.
