`Flyweight`__
|
|
=============
|
|
|
|
Purpose
|
|
-------
|
|
|
|
To minimise memory usage, a Flyweight shares as much as possible memory with similar objects. It
|
|
is needed when a large amount of objects is used that don't differ much in state. A common practice is
|
|
to hold state in external data structures and pass them to the flyweight object when needed.
