Method Summary

Modifier and Type	Method and Description
void	close() Called when an application calls Connection.close(), before the driver processes its own internal logic for close.
boolean	commit() Called when an application calls Connection.commit(), before the driver processes its own internal logic for commit().
void	destroy() Called by the driver when this extension should release any resources it is holding and cleanup internally before the connection is closed.
ConnectionLifecycleInterceptor	init(MysqlConnection conn, java.util.Properties props, Log log) Called once per connection that wants to use the extension The properties are the same ones passed in in the URL or arguments to Driver.connect() or DriverManager.getConnection().
boolean	rollback() Called when an application calls Connection.rollback(), before the driver processes its own internal logic for rollback().
boolean	rollback(java.sql.Savepoint s) Called when an application calls Connection.rollback(), before the driver processes its own internal logic for rollback().
boolean	setAutoCommit(boolean flag) Called when an application calls Connection.setAutoCommit(), before the driver processes its own internal logic for setAutoCommit().
boolean	setDatabase(java.lang.String db) Called when an application calls Connection.setCatalog() or Connection.setSchema(), before the driver processes its own internal logic for these methods.
boolean	transactionBegun() Called when the driver has been told by the server that a transaction is now in progress (when one has not been currently in progress).
boolean	transactionCompleted() Called when the driver has been told by the server that a transaction has completed, and no transaction is currently in progress.

Method Detail

close

public void close()
           throws java.sql.SQLException

Description copied from interface: ConnectionLifecycleInterceptor

Called when an application calls Connection.close(), before the driver processes its own internal logic for close.

Specified by:

close in interface ConnectionLifecycleInterceptor

Throws:

java.sql.SQLException - if an error occurs

commit

public boolean commit()
               throws java.sql.SQLException

Description copied from interface: ConnectionLifecycleInterceptor

Called when an application calls Connection.commit(), before the driver processes its own internal logic for commit(). Interceptors should return "true" if the driver should perform its own internal logic for commit(), or "false" if not.

Specified by:

commit in interface ConnectionLifecycleInterceptor

Returns:

"true" if the driver should perform its own internal logic for commit(), or "false" if not.

Throws:

java.sql.SQLException - if an error occurs

rollback

public boolean rollback()
                 throws java.sql.SQLException

Description copied from interface: ConnectionLifecycleInterceptor

Called when an application calls Connection.rollback(), before the driver processes its own internal logic for rollback(). Interceptors should return "true" if the driver should perform its own internal logic for rollback(), or "false" if not.

Specified by:

rollback in interface ConnectionLifecycleInterceptor

Returns:

"true" if the driver should perform its own internal logic for rollback(), or "false" if not.

Throws:

java.sql.SQLException - if an error occurs

rollback

public boolean rollback(java.sql.Savepoint s)
                 throws java.sql.SQLException

Description copied from interface: ConnectionLifecycleInterceptor

Called when an application calls Connection.rollback(), before the driver processes its own internal logic for rollback(). Interceptors should return "true" if the driver should perform its own internal logic for rollback(), or "false" if not.

Specified by:

rollback in interface ConnectionLifecycleInterceptor

Parameters:

s - savepoint

setAutoCommit

public boolean setAutoCommit(boolean flag)
                      throws java.sql.SQLException

Description copied from interface: ConnectionLifecycleInterceptor

Called when an application calls Connection.setAutoCommit(), before the driver processes its own internal logic for setAutoCommit(). Interceptors should return "true" if the driver should perform its own internal logic for setAutoCommit(), or "false" if not.

Specified by:

setAutoCommit in interface ConnectionLifecycleInterceptor

Parameters:

conn - the connection for which this extension is being created

props - configuration values as passed to the connection. Note that in order to support javax.sql.DataSources, configuration properties specific to an interceptor must be passed via setURL() on the DataSource. Extension properties are not exposed via accessor/mutator methods on DataSources.

log - logger instance

Returns:

interceptor
