Adapter
Adapter Design Pattern
Adapter, a Structural Pattern and also referred to as a wrapper, is most commonly used when you want to reuse a class to work with a target class but are constrained by incompatible interfaces. The idea is to convert the interface of a reusable class into an interface that your classes expect.
A good analogy for the Adapter pattern would be the adapter's commonly used to convert the voltage of Canadian/U.S made appliances to be used in different countries. In this case, the appliance (Target) is using the adapter (Adapter) to reuse the socket (Adaptee) already in place.
