Abstract
A development system providing a property-method-event programming (PME) model for developing context-free reusable software components is described. Despite the absence of any C++ language support for events, the present invention provides a type-safe 'wiring' mechanism--one using standard C++ to dispatch an event, raised by one object (the 'event source'), to a method of another object (the 'event sink'), with the requirement that the event source does not need to know the class of the event sink. As a result, the system allows developers to create C++ software components which can be connected together without the components having to know anything about the makeup of the component to which it is connected. Thus, developers can create pre-packaged, re-usable software components which can simply be 'plugged into' a design--all accomplished within the confines of the standard C++ programming language (i.e., without having to employ proprietary extensions).
