org.apache.avalon.excalibur.pool.ResourceLimitingPool
General Pool implementation which supports; weak and strong pool size limits, optional blocking gets when poolables are not available, and automatic pool trimming of unused poolables.
Whenever get() is called, the pool tests to see whether it is time to trim old poolables from the pool. If any old poolables exist then they are removed at this time. This means that old poolables will not be removed if get() is never called. Applications can optionally call trim() to force old objects to be trimmed. See the {@link #trim()} method for details of how trimming works. @author Avalon Development Team @version CVS $Revision: 1.5 $ $Date: 2004/03/29 16:50:37 $ @since 4.1
