Editing Adapter pattern (section)

== Usage ==
An adapter can be used when the wrapper must respect a particular interface and must support [[Polymorphism (computer science)|polymorphic]] behavior. Alternatively, a [[decorator pattern|decorator]] makes it possible to add or alter behavior of an interface at run-time, and a [[facade pattern|facade]] is used when an easier or simpler interface to an underlying object is desired.<ref name="Freeman_2004"/>
