Direct Known Subclasses:

public class ConnectionPoolDataSourceConnectionFactoryAdapter
extends JDBCConnectionFactoryAdapter

The connection factory adapter for javx.sql.ConnectionPoolDataSource. The physical connections that this adapter creates and closes are instances of javax.sql.PooledConnection. When the javax.sql.PooledConnection object is created, the connection pool that is associated with this adapter is registered as a javax.sql.ConnectionEventListener (assuming the connection pool is a javax.sql.ConnectionEventListener). The connection pool is deregistered when the javax.sql.PooledConnection object is closed.
