Editing Design Patterns (section)

===Structural===
[[Structural pattern]]s concern class and object composition. They use inheritance to compose interfaces and define ways to compose objects to obtain new functionality.
* [[Adapter pattern|Adapter]] allows classes with incompatible interfaces to work together by wrapping its own interface around that of an already existing class.
* [[Bridge pattern|Bridge]] decouples an abstraction from its implementation so that the two can vary independently.
* [[Composite pattern|Composite]] composes zero-or-more similar objects so that they can be manipulated as one object.
* [[Decorator pattern|Decorator]] dynamically adds/overrides behavior in an existing method of an object.
* [[Facade pattern|Facade]] provides a simplified interface to a large body of code.
* [[Flyweight pattern|Flyweight]] reduces the cost of creating and manipulating a large number of similar objects.
* [[Proxy pattern|Proxy]] provides a placeholder for another object to control access, reduce cost, and reduce complexity.
