Object pooling API.
</p>
<p>
The <code>org.apache.commons.pool</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><A HREF="../../../../org/apache/commons/pool/ObjectPool.html" title="interface in org.apache.commons.pool"><CODE>ObjectPool</CODE></A></dt>
<dd>
defines a simple object pooling interface, with methods for
borrowing instances from and returning them to the pool.
</dd>
<dt><A HREF="../../../../org/apache/commons/pool/PoolableObjectFactory.html" title="interface in org.apache.commons.pool"><CODE>PoolableObjectFactory</CODE></A></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>
<A HREF="../../../../org/apache/commons/pool/ObjectPoolFactory.html" title="interface in org.apache.commons.pool"><CODE>ObjectPoolFactory</CODE></A>
defines a simple factory for <code>ObjectPool</code>s, which may be
useful for some applications.
</p>
<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
<A HREF="../../../../org/apache/commons/pool/KeyedObjectPool.html" title="interface in org.apache.commons.pool"><CODE>KeyedObjectPool</CODE></A>,
<A HREF="../../../../org/apache/commons/pool/KeyedPoolableObjectFactory.html" title="interface in org.apache.commons.pool"><CODE>KeyedPoolableObjectFactory</CODE></A>,
and
