| Object pooling API. |
| </p> |
| <p> |
| The <code>org.apache.tomcat.dbcp.pool2</code> package defines a simple |
| interface for a pool of object instances, and a handful of base |
| classes that may be useful when creating pool implementations. |
| </p> |
| <p> |
| The <code>pool</code> package itself doesn't define a specific object |
| pooling implementation, but rather a contract that implementations may |
| support in order to be fully interchangeable. |
| </p> |
| <p> |
| The <code>pool</code> package separates the way in which instances are |
| pooled from the way in which they are created, resulting in a pair of |
| interfaces: |
| </p> |
| <dl> |
| <dt>{@link org.apache.tomcat.dbcp.pool2.ObjectPool ObjectPool}</dt> |
| <dd> |
| defines a simple object pooling interface, with methods for |
| borrowing instances from and returning them to the pool. |
| </dd> |
| <dt>{@link org.apache.tomcat.dbcp.pool2.PooledObjectFactory PooledObjectFactory}</dt> |
| <dd> |
| defines lifecycle methods for object instances contained within a pool. |
| By associating a factory with a pool, the pool can create new object |
| instances as needed. |
| </dd> |
| </dl> |
| <p> |
| The <code>pool</code> package also provides a keyed pool interface, |
| which pools instances of multiple types, accessed according to an |
| arbitrary key. See |
| {@link org.apache.tomcat.dbcp.pool2.KeyedObjectPool KeyedObjectPool} and |
| {@link org.apache.tomcat.dbcp.pool2.KeyedPooledObjectFactory |
| KeyedPooledObjectFactory}. |
