| KeyedCPDSConnectionFactory | | public KeyedCPDSConnectionFactory(ConnectionPoolDataSource cpds, KeyedObjectPool pool, String validationQuery)(Code) | | Create a new KeyedPoolableConnectionFactory.
Parameters:
cpds - the ConnectionPoolDataSource from which to obtain PooledConnection's
Parameters:
pool - the {*link ObjectPool} in which to pool those {*link Connection}s
Parameters:
validationQuery - a query to use to {*link #validateObject validate} {*link Connection}s. Should return at least one row. May be null |
| connectionClosed | | public void connectionClosed(ConnectionEvent event)(Code) | | This will be called if the Connection returned by the getConnection
method came from a PooledConnection, and the user calls the close()
method of this connection object. What we need to do here is to
release this PooledConnection from our pool...
|
| connectionErrorOccurred | | public void connectionErrorOccurred(ConnectionEvent event)(Code) | | If a fatal error occurs, close the underlying physical connection so as
not to be returned in the future
|
| getPool | | public KeyedObjectPool getPool()(Code) | | |
| makeObject | | public synchronized Object makeObject(Object key) throws Exception(Code) | |
Parameters:
key -
throws:
SQLException - if the connection could not be created.

| setPool | | public synchronized void setPool(KeyedObjectPool pool) throws SQLException(Code) | | Sets the {*link ObjectPool} in which to pool {*link Connection}s.
Parameters:
pool - the {*link ObjectPool} in which to pool those {*link Connection}s |
| setRollbackAfterValidation | | public synchronized void setRollbackAfterValidation(boolean rollbackAfterValidation)(Code) | | Sets whether a rollback should be issued after
{*link #validateObject validating}
{*link Connection}s.
Parameters:
rollbackAfterValidation - whether a rollback should be issued after{*link #validateObject validating} {*link Connection}s. |
| setValidationQuery | | public synchronized void setValidationQuery(String validationQuery)(Code) | | Sets the query I use to {*link #validateObject validate} {*link Connection}s.
Should return at least one row.
May be null
