Template Method Pattern

• Template Method Design Pattern

Intent

    Define the skeleton of an algorithm in an operation, deferring some steps to client subclasses. Template Method lets subclasses redefine certain steps of an algorithm without changing the algorithm’s structure.

Rules of thumb

    Strategy is like Template Method except in its granularity.
    Template Method uses inheritance to vary part of an algorithm. Strategy uses delegation to vary the entire algorithm.
    Strategy modifies the logic of individual objects. Template Method modifies the logic of an entire class.
    Factory Method is a specialization of Template Method.

• Template method pattern

 the template method pattern is a behavioral design pattern that defines the program skeleton of an algorithm in a method, called template method, which defers some steps to subclasses. It lets one redefine certain steps of an algorithm without changing the algorithm's structure
