方法详细资料

initialize

public void initialize(Connection conn,
                       Properties configurationProps)
                throws SQLException

从接口复制的说明: ClientInfoProvider

Called once by the driver when it needs to configure the provider.

指定者:

initialize 在接口中 ClientInfoProvider

参数:

conn - the connection that the provider belongs too.

configurationProps - a java.util.Properties instance that contains configuration information for the connection.

抛出:

SQLException - if initialization fails.

destroy

public void destroy()
             throws SQLException

从接口复制的说明: ClientInfoProvider

Called once by the driver when the connection this provider instance belongs to is being closed. Implementations are expected to clean up and resources at this point in time.

指定者:

destroy 在接口中 ClientInfoProvider

抛出:

SQLException - if an error occurs.

getClientInfo

public Properties getClientInfo(Connection conn)
                         throws SQLException

从接口复制的说明: ClientInfoProvider

Returns the client info for the connection that this provider instance belongs to. The connection instance is passed as an argument for convenience's sake. Providers can use the connection to communicate with the database, but it will be within the scope of any ongoing transactions, so therefore implementations should not attempt to change isolation level, autocommit settings or call rollback() or commit() on the connection.

指定者:

getClientInfo 在接口中 ClientInfoProvider

参数:

conn - connection object

返回:

client info as Properties

抛出:

SQLException - if an error occurs
