Facade

Type: Structural Pattern

Structure:

In my Codes(Role - Classes):

  • Facade: ShapeMaker
  • Subsystem Classes: Shape, Circle, etc..

Key Points

  • Facade should know which subsystem classes are responsible for a request
  • Facade delegates client requests to appropriate subsystem objects
  • Subsystem classes implement subsystem functionally, handle works assigned by the facade
  • Subsystem classes have no knowledge of the facade
