DataNotAvailableException

close

public void close()
           throws ConnectorException

Description copied from interface: Execution

Terminates the execution normally.

Specified by:

close in interface Execution

Throws:

ConnectorException

cancel

public void cancel()
            throws ConnectorException

Description copied from interface: Execution
