Design Smarter : The Template Method Approach
Template Method Pattern The Template Method Pattern is a behavioral design pattern that defines the skeleton of an algorithm in a method, deferring some steps to subclasses. It allows subclasses to override certain steps of the algorithm without changing its structure. The pattern promotes code reuse and helps in defining a common structure for a group of related algorithms. Key Participants: Abstract Class · Defines the template method (templateMethod()) that outlines the steps of the algorithm. This method typically consists of a sequence of method calls, some of which are abstract and need to be implemented by subclasses. May contain concrete methods that are shared across all subclasses. Concrete Classes: · Subclasses of the abstract class that implement the abstract methods defined in the template method. · ...
