Software engineers are taught that they should separate form and function. This allows a user interface or front-end to be designed and implemented independently of the engine or back-end. Using an abstracted interface class provides the opportunity to develop different user interfaces for the same back-end, as each new user interface will all be derived from this agreed upon abstracted interface. Using the Bridge pattern allows the user to also decouple the abstraction from its implementation, providing additional flexibility as they developed multiple user interfaces. However, user interfaces are typically designed as a single unit, the renderer, even the Bridge pattern refers to it as the ConcreteImplementor. This thesis concentrated on the implementation of the renderer and merged the Bridge pattern with another design pattern, the Presentation Model. The Extended Bridge pattern also includes support for the Single Responsibility principle; a construct that improves upon the Presentation Model by decoupling the logic and the data from the rendering code. In short the Extended Bridge is an object oriented pattern that provides an abstract interface, an abstract implementation with decoupled logic, data and rendering, that is flexible, maintainable, reusable and highly testable.
