Flyweight

This is a UML class diagram example for the Flyweight design pattern.

Purpose

Facilitates the reuse of many fine grained objects, making the utilization of large numbers of objects more efficient.

Use When

  • Many like objects are used and storage cost is high.
  • The majority of each object's state can be made extrinsic.
  • A few shared objects can replace many unshared ones.
  • The identity of each object does not matter.
