26 | * Base abstraction for any Design Pattern type whose structure is based on | |
27 | * surrogation or wrapping. Surrogate Design Patterns are those that for some | |
28 | * purpose wrap and provide to clients the same interface view of the actual | |
29 | * wrapped <code>Component</code> interface. <br/><br/> | |
30 | * | |
31 | * Structural surrogate Patterns are: | |
32 | * | |
33 | * <ul> | |
34 | * <li>Adapter Pattern</li> | |
35 | * <li>Composite Pattern</li> | |
36 | * <li>Decorator Pattern</li> | |
37 | * <li>Proxy Pattern</li> | |
