Abstract
In scripting connections between objects within a component software architecture, a generic event processing module is provided to listen to all possible events. Objects registered for scripting are introspected to determine all events which may be fired by the object. In the case of the Java beans specification, this includes both Java-defined and user-defined events. One or more event listener classes for user-defined events may then be created, instantiated and added to the registered objects at runtime. When an event is fired and detected by a system listener, the appropriate event listener notifies the client, which may be a scripting component. The client may then take appropriate action. With an event processing module as described, event sinks need not be wrapped to become event listeners and event sources need not be wrapped to generate events in a specific manner. Events may be passed between sources and sinks without either knowing of the existence of the other.
