MysqlPooledConnection

public MysqlPooledConnection(JdbcConnection connection)

Construct a new MysqlPooledConnection and set instance variables

参数:

connection - physical connection to db

方法详细资料

getInstance

protected static MysqlPooledConnection getInstance(JdbcConnection connection)
                                            throws SQLException

抛出:

SQLException

addConnectionEventListener

public void addConnectionEventListener(ConnectionEventListener connectioneventlistener)

指定者:

addConnectionEventListener 在接口中 PooledConnection

removeConnectionEventListener

public void removeConnectionEventListener(ConnectionEventListener connectioneventlistener)

指定者:

removeConnectionEventListener 在接口中 PooledConnection

getConnection

public Connection getConnection()
                         throws SQLException

指定者:

getConnection 在接口中 PooledConnection

抛出:

SQLException

getConnection

protected Connection getConnection(boolean resetServerState,
                                   boolean forXa)
                            throws SQLException

抛出:

close

public void close()
           throws SQLException

Invoked by the container (not the client), and should close the physical connection. This will be called if the pool is destroyed or the connectionEventListener receives a connectionErrorOccurred event.

指定者:

close 在接口中 PooledConnection

抛出:

SQLException

callConnectionEventListeners

protected void callConnectionEventListeners(int eventType,
                                            SQLException sqlException)

Notifies all registered ConnectionEventListeners of ConnectionEvents. Instantiates a new ConnectionEvent which wraps sqlException and invokes either connectionClose or connectionErrorOccurred on listener as appropriate.

参数:

eventType - value indicating whether connectionClosed or connectionErrorOccurred called

sqlException - the exception being thrown

getExceptionInterceptor

protected ExceptionInterceptor getExceptionInterceptor()

addStatementEventListener

public void addStatementEventListener(StatementEventListener listener)

指定者:

addStatementEventListener 在接口中 PooledConnection

removeStatementEventListener

public void removeStatementEventListener(StatementEventListener listener)

指定者:

removeStatementEventListener 在接口中 PooledConnection
