### MappingCommAreaOperation

    public MappingCommAreaOperation()

  Create a new MappingCommAreaQuery.

  See Also:
    `EisOperation.setConnectionFactory(javax.resource.cci.ConnectionFactory)`, `EisOperation.setInteractionSpec(javax.resource.cci.InteractionSpec)`

### MappingCommAreaOperation

    public MappingCommAreaOperation(ConnectionFactory connectionFactory,
                                    InteractionSpec interactionSpec)

  Create a new MappingCommAreaQuery.

  Parameters:
    `connectionFactory` - ConnectionFactory to use to obtain connections
    `interactionSpec` - specification to configure the interaction

Method Detail

### createInputRecord

    protected final Record createInputRecord(RecordFactory recordFactory,
                                             Object inObject)

  Description copied from class: `MappingRecordOperation`
  Subclasses must implement this method to generate an input Record from an input object passed into the `execute` method.

  Specified by:
    `createInputRecord` in class `MappingRecordOperation`
    `inObject` - the passed-in input object
  Returns:
    the CCI input Record
  See Also:
    `MappingRecordOperation.execute(Object)`

### extractOutputData

    protected final Object extractOutputData(Record record)
                                      throws DataAccessException

  Description copied from class: `MappingRecordOperation`
  Subclasses must implement this method to convert the Record returned by CCI execution into a result object for the `execute` method.

  Specified by:
    `extractOutputData` in class `MappingRecordOperation`
  Parameters:
    `record` - the Record returned by CCI execution
  Returns:
    the result object
  Throws:
    `DataAccessException`
  See Also:
    `MappingRecordOperation.execute(Object)`

### objectToBytes

    protected abstract byte[] objectToBytes(Object inObject)
                                     throws IOException,
                                            DataAccessException

  Method used to convert an object into COMMAREA bytes.

  Parameters:
    `inObject` - the input data
  Returns:
    the COMMAREA's bytes
  Throws:
    `IOException` - if thrown by I/O methods
    `DataAccessException` - if conversion failed

### bytesToObject

    protected abstract Object bytesToObject(byte[] bytes)
                                     throws IOException,
                                            DataAccessException

  Method used to convert the COMMAREA's bytes to an object.

  Parameters:
    `bytes` - the COMMAREA's bytes
  Returns:
