Chain of Responsibility

This is a UML class diagram example for the Chain of Responsibility design pattern.

Purpose

Gives more than one object an opportunity to handle a request by linking receiving objects together.

Use When

  • Multiple objects may handle a request and the handler doesn't have to be a specific object.
  • A set of objects should be able to handle a request with the handler determined at runtime.
  • A request not being handled is an acceptable potential outcome.
