object single responsibility :

  • Information holder – an object designed to know certain information and provide that information to other objects.
  • Structurer – an object that maintains relationships between objects and information about those relationships.
  • Service provider – an object that performs specific work and offers services to others on demand.
  • Controller – an object designed to make decisions and control a complex task.
  • Coordinator – an object that doesn’t make many decisions but, in a rote or mechanical way, delegates work to other objects.
  • Interfacer – an object that transforms information or requests between distinct parts of a system.
