Composite

Difficulty-Intermediate Gang Of Four Java Structural

Intent

Compose objects into tree structures to represent part-whole hierarchies. Composite lets clients treat individual objects and compositions of objects uniformly.

alt text

Applicability

Use the Composite pattern when

  • you want to represent part-whole hierarchies of objects
  • you want clients to be able to ignore the difference between compositions of objects and individual objects. Clients will treat all objects in the composite structure uniformly
