Class PoolingConnection

public class PoolingConnection extends DelegatingConnection implements Connection, KeyedPoolableObjectFactory

A DelegatingConnection that pools PreparedStatements.

My PoolingConnection methods, rather than creating a new PreparedStatement each time, may actually pull the PreparedStatement from a pool of unused statements. The PreparedStatement#close method of the returned PreparedStatement doesn't actually close the statement, but rather returns it to my pool. (See PoolablePreparedStatement.)
