Method Detail

getConnectionKiller

public java.lang.Runnable getConnectionKiller(DatabaseIdentifier databaseIdentifier,
                                              java.sql.Connection conn)

Description copied from interface: IConnectionService

Returns a Runnable which can be used to kill the connection. This Runnable instance will be used to terminate a running statement. This is necessary because jdbc.sql.Statement.cancel() and jdbc.sql.Connection.close() wonĄŻt always be able to do the job.

Specified by:

getConnectionKiller in interface IConnectionService

Parameters:

databaseIdentifier - uniquely identifies a database

conn - the connection object

Returns:

a Runnable which can be used to kill the connection.

getConnectionId

public int getConnectionId(DatabaseIdentifier databaseIdentifier,
                           java.sql.Connection conn)

Description copied from interface: IConnectionService

Returns an identifier for the connection. This id should be unique across all clients.

Specified by:

getConnectionId in interface IConnectionService

Parameters:

databaseIdentifier - uniquely identifies a database

conn - the connection object

Returns:

an identifier for the connection

createControlConnection

public IControlConnection createControlConnection(DatabaseIdentifier databaseIdentifier)
                                           throws java.sql.SQLException

Description copied from interface: IConnectionService

Returns an IControlConnection object which is used for all shared usage to that particular database.

Specified by:

createControlConnection in interface IConnectionService

Parameters:

databaseIdentifier - uniquely identifies a database

Returns:

an IControlConnection object which is used for all shared usage to that particular database.

Throws:

java.sql.SQLException

getConnectionInitializer

public IConnectionInitializer getConnectionInitializer()

Description copied from interface: IConnectionService

Returns a IConnectionInitializer object which is used to initialize connection to proper state. Clients may want to let end user customize the connection status by providing preference pages. The extension point preferenceSections is interesting to data server vendors if they want to contribute preference controls to an existing DTP preference page.

Specified by:

getConnectionInitializer in interface IConnectionService

Returns:

a IConnectionInitializer object which is used to initialize connection to proper state.
