Strategy Pattern
Explore the strategy pattern to understand how it encapsulates related algorithms under a common interface, allowing clients to switch algorithms seamlessly. This lesson demonstrates applying the pattern with examples like sorting algorithms and weapon strategies for an aircraft scenario. You will learn to decouple clients from implementations, enhancing code flexibility and maintainability.
We'll cover the following...
What is it ?
The strategy pattern is one of the simpler patterns to comprehend. It allows grouping related algorithms under an abstraction, which the client codes against. The abstraction allows switching out one algorithm or policy for another without modifying the client.
The strategy pattern is formally defined as encapsulating algorithms belonging to the same family and making them interchangeable. The consumers of the common interface that the algorithms implement allow switching out one algorithm for another seamlessly.
