The Mediator Pattern

· Java Zone

Check out this 8-step guide to see how you can increase your productivity by skipping slow application redeploys and by implementing application profiling, as you code! Brought to you in partnership with ZeroTurnaround.

Description:

It defines an object that encapsulates how a set of objects interact. Mediator promotes loose coupling by keeping objects from referring to each other explicitly, and it lets you vary their interaction independently

Benefits:

  •  Decouples colleagues
  •  Simplifies object protocols
  •  Centralizes control

When to use:

  • A set of objects communicate in well-defined but complex ways.
  • You want to customize a behavior that’s distributed between several objects without using subclasses.
