Sample text

0 class inherits everything in the Sprite class, the application should still work. As you will see, it works just fine. The reason that Sprite is used instead of MovieClip is that we did not want to have any unnecessary baggage—just the minimum we needed. If you change Sprite to the next class it inherits from, DisplayObjectContainer, you will see that the application fails. This means that the application requires one of the Sprite class properties that is not inherited. One byte over the line: in Example 1-9, if you substitute the MovieClip for Sprite classes for the parent class, you will find that your SWF file is larger than when you tested it with Sprite (708 bytes versus 679 bytes).

If the ability to add more behaviors easily is most important, then abstract classes are a better choice. Alternatively, if you want independence from the base class, then choose an interface structure. No matter what you do, though, you need to think ahead beyond the first version of your application. If your application is built with an eye to future versions and possible ways that it can expand or change, you can better judge what design pattern would best achieve your goals. 0 Using Complex Interfaces As you saw in Example 1-36, the program typed the instances to the implementation and not the interfaces as was done in Example 1-20.

By doing so, you separate the client from the implementation as well. 0 interface structure or an abstract class to set up this kind of flexible dependence. However, when you use either, you must be aware of the way in which to manage the dependency. If you use an interface structure, any change in the interface will cause failure in all the clients that use the interface. For example, suppose you have five methods in an interface. You decide that you need two more. As soon as you add the two new methods to your interface, your client is broken.
