Class WeakPool<T>

  • 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.
