Class NotifyPooler

java.lang.Object
  org.ascentphase.poolit.poolers.NotifyPooler

All Implemented Interfaces:

Pooler

public class NotifyPooler

extends java.lang.Object

implements Pooler

Notifies objects when they are fetched from and released to the pool. This Pooler works by notifying objects in the pool that implement the NotifyPoolListener when the object leaves the pool and is returned to the pool. If the object does not implement NotifyPoolListener, nothing happens. This class wraps another Pooler that implements a specific pooling algorithm and permits notification of objects when leaving/entering the pool.
