Method Detail

next

public java.util.List<?> next()
                       throws ConnectorException,
                              DataNotAvailableException

Specified by:

next in interface ResultSetExecution

Throws:

ConnectorException

DataNotAvailableException

execute

public void execute()
             throws ConnectorException

Description copied from interface: Execution

Execute the associated command. Results will be retrieved through a specific sub-interface call.

Specified by:

execute in interface Execution

Throws:

ConnectorException

getUpdateCounts

public int[] getUpdateCounts()
                      throws DataNotAvailableException,
                             ConnectorException

Specified by:

getOutputParameterValues

public java.util.List<?> getOutputParameterValues()
                                           throws ConnectorException

Description copied from interface: ProcedureExecution

Get the output parameter values. Results should place the return parameter first if it is present, then the IN/OUT and OUT parameters should follow in the order they appeared in the command.

Specified by:

getOutputParameterValues in interface ProcedureExecution

Throws:

ConnectorException - If an error occurs while retrieving the output value

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

Cancels the execution abnormally. This will happen via a different thread from the one performing the execution, so should be expected to happen in a multi-threaded scenario.
