All Implemented Interfaces:
IPool<T>
public class WeakPool<T> extends Object implements IPool<T>
An object pool backed by weak references. Objects stored in this pool will be garbage collected once all strong references to the objects are broken.

Since WeakReference are not particularly light-weight, a client could use a StrongPool if the pool will be short lived and explicitly nulled by the client.
