Class FlyweightFactory

public class FlyweightFactory
extends Object
The Flyweight factory maintains a pool of instantiated flyweights. When the client requests a shareable flyweight, the factory first searches the pool to see if there is already one available. If it is, the factory simply returns that instance. Otherwise it instantiates a new flywieght, adds it to the pool and returns a reference to the client.
