Interface IPool<T>

All Known Implementing Classes:
StrongPool, WeakPool
public interface IPool<T>
A Pool allows semantically equivalent objects to be shared. To be useful, objects added to the pool should implement a meaningful equals() method.

Care must be taken by users that object sharing is appropriate for their application. It is easy to "over share" objects leading to unexpected and difficult to debug behaviour.

This interface is not intended to be implemented by clients.
