Class CollectionObjectPoolFactory

java.lang.Object
  nl.knowledgeplaza.util.pool.CollectionObjectPoolFactory

All Implemented Interfaces:

PoolableObjectFactory

public class CollectionObjectPoolFactory
extends java.lang.Object
implements PoolableObjectFactory

This class is a simple implementation of an ObjectPoolFactory. A new instance of this class is provided with a list of values that are pooled. The instance can be handed over to a StackObjectPool or a RoundRobinObjectPool to provide pooling behaviour. Making a new object means that one object is removed from the list and handed over to the pool to be managed. If the list is empty, null will be returned. It is up to the pool to decide if it will then wait or abort. Objects are always considered valid, and no action is take to activate or destroy them. These methods can be overridden. Destroyed objects are added back to the list if RecycleObjects = true.
