## Strategy
|
|
|
|
Strategy defines a family of algorithms, encapsulates each one, and makes them
|
|
interchangeable. It lets the algorithm vary independently fromclients that use it.
|
|
The pattern has behavioral purpose and applies to the objects.
|
|
|
|
### When to use
|
|
|
|
* many related classes differ only in their behavior
|
|
* you need different variants of an algorithm
|
|
* an algorithm uses data that clients shouldn't know about |
