Implementing Run-time Support for Components using Object-Oriented Programming

ions That Guide Component Implementation We implement components by trying to be first of all good designers and secondly by following the Java Beans “design pattern” conventions. In this way we can benefit from the powerful introspection mechanism of Java Beans. [2] Identifies three technical features that need to be supported by component-oriented programming: component containment, multiple instances of component interfaces, and interface dispatch. We implemented ORB components with these three features in mind. This led to the design of a simple white-box framework by identifying common features, like method dispatching and containment invariants. These features were generalized into generic classes such as a hierarchy
