org.datanucleus.store.rdbms.datasource.dbcp.PoolingConnection

A {@link DelegatingConnection} that pools {@link PreparedStatement}s.

The {@link #prepareStatement} and {@link #prepareCall} methods, rather than creating a new PreparedStatementeach time, may actually pull the statement from a pool of unused statements. The {@link PreparedStatement#close} method of the returned statement doesn'tactually close the statement, but rather returns it to the pool. (See {@link PoolablePreparedStatement}, {@link PoolableCallableStatement}.) @see PoolablePreparedStatement @author Rodney Waldhoff @author Dirk Verbeeck @version $Revision: 885261 $ $Date: 2009-11-29 15:07:02 -0500 (Sun, 29 Nov 2009) $
