Not everyone can be the most popular. A lot has changed in the last 10 years. Since Design Patterns: Elements of Reusable Object-Oriented Software first came out, developers have applied these patterns thousands of times. The patterns we summarize in this appendix are full-fledged, card-carrying, official GoF patterns, but aren’t used as often as the patterns we’ve explored so far. But these patterns are awesome in their own right, and if your situation calls for them, you should apply them with your head held high. Our goal in this appendix is to give you a high level idea of what these patterns are all about.
Use the Bridge Pattern to vary not only your implementations, but also your abstractions.
Imagine you’re going to revolutionize “extreme lounging.” You’re writing the code for a new ergonomic and user-friendly remote control for TVs. You already know that you’ve got to use good OO techniques because while the remote is based on the same abstraction, there will be lots of implementations – one for each model of TV.
You know that the remote’s user interface won’t be right the first time. In fact, you expect that the product will be refined many times as usability data is collected on the remote control.
So your dilemma ...
