Design Inheritance is a common way to specify different implementations of an abstraction. However, the implementations are then bound tightly to the abstraction, and it is difficult to modify them independently. The Bridge pattern provides an alternative to inheritance when there is more than one version of an abstraction. Consider the UML diagram in Figure 2-8. The two implementations, A and B, implement an interface called the Bridge. The Abstraction includes an attribute of type Bridge but is not otherwise in a relationship with the implementations.

At a more mundane level, decorators abound in the I/O APIs of C#. CryptoStream The subclasses decorate Stream because they inherit from it, and they also contain an instance of a Stream that is set up when an object is constructed. Many of their properties and methods relate to this instance. 20 | Chapter 2: Structural Patterns: Decorator, Proxy, and Bridge • In today’s world of mobile devices, web browsers and other mobile applications thrive on the Decorator pattern. They can create display objects suitable for smaller screens that include scroll bars and exclude banners that would be standard on desktop display browsers, for example.

In this table, types include classes, structs, interfaces, enums, and delegates. The interpretation of this table for classes is as follows: • A non-nested class is by default visible to other classes in the same assembly. • A nested class is by default private and can have no more accessibility than its enclosing class. , field, method, property) is by default private. • An inherited class can have special access to a member in its superclass that has been tagged with the protected modifier. Unless you are going to do cross-assembly development, the public modifier is not strictly necessary; however, it has a currency in programming that the internal modifier does not.
