Template Method Pattern
The Template Method Pattern is a behavioral design pattern that defines the skeleton of an algorithm in a base class, allowing subclasses to override specific steps without changing the algorithm's structure. It promotes code reuse by encapsulating invariant parts of an algorithm while letting subclasses define variable parts. This pattern is commonly used in frameworks and libraries to provide extensible behavior.
Developers should use this pattern when they have multiple classes that share a common algorithm but differ in some implementation details, such as in GUI frameworks, data processing pipelines, or game engines. It helps avoid code duplication and ensures consistency in the overall algorithm flow while allowing flexibility in specific steps, making it ideal for building reusable and maintainable software components.
