Strategy pattern

|
In computer programming, the strategy pattern is a particular software design pattern, whereby algorithms can be selected on-the-fly at runtime depending on conditions, like strategies in a war situation.
The strategy pattern is useful for situations where it is necessary to dynamically swap the algorithms used in an application. The strategy pattern is intended to provide a means to define a family of algorithms, encapsulate each one as an object, and make them interchangeable. The strategy pattern lets the algorithms vary independently from clients that use them.
