Package org.apache.commons.pool2.impl

package org.apache.commons.pool2.impl

Object pooling API implementations.

GenericObjectPool (GenericKeyedObjectPool) provides a more robust (but also more complicated) implementation of ObjectPool (KeyedObjectPool).

SoftReferenceObjectPool provides a SoftReference based ObjectPool.
