What it is:
Convert the interface of a class into
another interface clients expect. Lets classes work together that couldn't otherwise because of incompatible interfaces. +adaptedOperation()Adaptee

Type:Structural
What it is:
Decouple an abstraction from its

Compose objects into tree structures to

Type:Structural
What it is:
Attach additional responsibilities to an
object dynamically. Provide a flexible alternative to sub-classing for extending functionality.Facade
Type:Structural
What it is:
Provide a unified interface to a set of
interfaces in a subsystem. Defines a high- level interface that makes the subsystem easier to use.Flyweight

Use sharing to support large numbers of
fine grained objects efficiently. +request()RealSubject
