DuckAdapter

Duck Adapter

In the class diagram below you can see the Adapter Pattern in play: In this example, the TurkeyAdapter class implements the Duck interface, expected by the Client, and delegates the requests to the adaptee (WildTurkey). Notice that in the implementation, one of the methods had to be changed slightly by the adapter itself before delegating the call to the adaptee.
