| <h3>1. INTRODUCTION</h3> |
| |
| <p>The <em>Pool</em> package defines a generalized object pooling interfaces, |
| and provides several general-purpose implementations. |
| The following major classes are provided: |
| |
| <ul> |
| <li><strong>ObjectPool</strong> - the basic pooling interface, defining |
| borrowObject, returnObject and several optional methods.</li> |
| <li><strong>KeyedObjectPool</strong> - a pooling interface that supports pooling |
| multiple <em>typed</em> objects.</li> |
| <li><strong>PoolableObjectFactory</strong> - interface defining |
| lifecycle methods for object instances used within an ObjectPool. |
| <li><strong>KeyedPoolableObjectFactory</strong> - interface defining |
| lifecycle methods for object instances used within a KeyedObjectPool. |
| <li><strong>StackObjectPool/StackKeyedObjectPool</strong> - implementations |
| of ObjectPool and KeyedObjectPool backed by a simple Stack of |
| pooled instances</li> |
| <li><strong>GenericObjectPool/GenericKeyedObjectPool</strong> - more |
| complex implementations of ObjectPool and KeyedObjectPool, supporting |
| asynchronous eviction of pooled instances, etc.</li> |
| </ul> |
| |
| <a name="Dependencies"></a> |
| <h3>2. DEPENDENCIES</h3> |
| |
| <p>The <em>Pool</em> package is dependent upon the following external |
| components for development and use:</p> |

| (Version 1.2 or later)</li> |
| <li>Jakarta-Commons Collections package (Version 1.0 or later)</li> |
| <li><a href="http://www.junit.org">JUnit Testing Framework</a> |
| (Version 3.2 or later) - for unit tests only, not required |
| for deployment</li> |
| </ul> |
| |
