Template Method

This is a UML class diagram example for the template method pattern.

Purpose

Identifies the framework of an algorithm, allowing implementing classes to define the actual behavior.

Use When

• A single abstract implementation of an algorithm is needed.
• Common behavior among subclasses should be localized to a common class.
• Parent classes should be able to uniformly invoke behavior in their subclasses.
• Most or all subclasses need to implement the behavior.
