Singleton

THIS IS CONSIDERED TO BE AN ANTI-PATTERN! FOR BETTER TESTABILITY AND MAINTAINABILITY USE DEPENDENCY INJECTION!

Purpose

To have only one instance of this object in the application that will handle all calls.

Examples

  • DB Connector
  • Logger (may also be a Multiton if there are many log files for several purposes)
  • Lock file for the application (there is only one in the filesystem ...)
