Chapter 22. Flyweight > Motivation

Motivation

Within Cocoa, flyweights are primarily used for the following three reasons:

  • Flyweights encapsulate nonobject data so that the data can be used in contexts where objects are required.

  • Flyweights reduce storage requirements when a large number of instances are needed.

  • Flyweights act as stand-ins for other objects.
