    - #### DSResponse

          public DSResponse(java.lang.String dataSource,
                            DSOperationType operationType)

    - #### DSResponse

          public DSResponse(java.lang.String dataSource,
                            DSOperationType operationType,
                            Record... data)

  - ### Method Detail

    - #### getOrCreateRef

          public static DSResponse getOrCreateRef(com.google.gwt.core.client.JavaScriptObject jsObj)

    - #### getData

          public Record[] getData()

      For "fetch" operations, this is the array of Records fetched. For "update", "add", and "remove" operations, this is typically an array containing a single Record representing the record that was updated, added, or removed.
      Returns:
        Current data value. Default value is null

    - #### getDataAsRecordList

          public RecordList getDataAsRecordList()

      For "fetch" operations, this is the array of Records fetched. For "update", "add", and "remove" operations, this is typically an array containing a single Record representing the record that was updated, added, or removed.
      Returns:
        Current data value. Default value is null

    - #### setDataSource

          public DSResponse setDataSource(java.lang.String dataSource)

      The DataSource of this DSResponse.
      Parameters:
        `dataSource` - New dataSource value. Default value is null
      Returns:
        `DSResponse` instance, for chaining setter calls

    - #### getDataSource

          public java.lang.String getDataSource()

      The DataSource of this DSResponse.
      Returns:
        Current dataSource value. Default value is null

    - #### getEndRow

          public java.lang.Integer getEndRow()

      End row of returned server results, when using paged result fetching

      Note that startRow and endRow are zero-based, inclusive at the beginning and exclusive at the end (like substring), so startRow: 0, endRow: 2 is a response containing two records.

      Returns:
        Current endRow value. Default value is null

    - #### getEstimatedTotalRows

          public java.lang.String getEstimatedTotalRows()

      This attribute may be set for responses where `progressive loading` is active to indicate the estimated true total row count for the data set. In progressive loading mode, `totalRows` can be thought of as an indication of the last row the user is allowed to request (EG by scrolling through a databound ListGrid), whereas `estimatedTotalRows` can convey the server's knowledge of the number of matching rows to the client.

      This value may be validly set to a String in the following format:

      - "500+": There are at least 500 records
      - "-500": There are fewer than 500 records
      - "450-500": There are between 450 and 500 records
      - "~500": There are approximately 500 records
      - "500": There are exactly than 500 records
      If you are using a Smart GWT server side dataSource that supports the `DataSource.progressiveLoadingThreshold` feature, this property will be populated automatically to an exact value if a row count query was performed and the result exceeded the progressiveLoadingThreshold causing progressiveLoading to be enabled.

      Developers may also write custom dataSource logic to populate this attribute if desired

      Returns:
        Current estimatedTotalRows value. Default value is null

    - #### getFromOfflineCache

          public java.lang.Boolean getFromOfflineCache()

      If set, indicates that this response came from the offline cache, not the server. This flag is the only reliable way for application code to determine the source of a response.
      Returns:
        Current fromOfflineCache value. Default value is null

    - #### getHttpHeaders

          public java.util.Map getHttpHeaders()

      HTTP headers returned by the server as a map from header name to header value.

      Headers are available only when the default `RPCTransport` "xmlHttpRequest" is in use, and browsers may limit access to headers for cross-domain requests or in other security-sensitive scenarios.

      Overrides:
        `getHttpHeaders` in class `RPCResponse`
      Returns:
        Current httpHeaders value. Default value is null

    - #### getInvalidateCache

          public java.lang.Boolean getInvalidateCache()

      Optional flag that can be set by the server to force ResultSets to drop any caches of records from the DataSource that was the target of the operation.
      Returns:
        Current invalidateCache value. Default value is null

    - #### getOfflineTimestamp

          public java.lang.Integer getOfflineTimestamp()

      Timestamp (millisecond value) to indicate when this dsResponse was cached in `offline storage`. Not applicable if the response has never been stored offline.
      Returns:
        Current offlineTimestamp value. Default value is null

    - #### setOperationId

          public DSResponse setOperationId(java.lang.String operationId)

      The operation ID of the request corresponding to this DSResponse.
      Parameters:
        `operationId` - New operationId value. Default value is null
      Returns:
        `DSResponse` instance, for chaining setter calls

    - #### getOperationId

          public java.lang.String getOperationId()

      The operation ID of the request corresponding to this DSResponse.
      Returns:
        Current operationId value. Default value is null

    - #### setOperationType

          public DSResponse setOperationType(DSOperationType operationType)

      The operation type of the request corresponding to this DSResponse.
      Parameters:
        `operationType` - New operationType value. Default value is null
      Returns:
        `DSResponse` instance, for chaining setter calls

    - #### getOperationType

          public DSOperationType getOperationType()

      The operation type of the request corresponding to this DSResponse.
      Returns:
        Current operationType value. Default value is null

    - #### getProgressiveLoading

          public java.lang.Boolean getProgressiveLoading()

      This attribute may be set to indicate that `progressive loading is enabled`, for a paged data fetch, and as such the `total row count` is not guaranteed to be accurate. Client side code, including the `ResultSet.lengthIsProgressive()` method may make use of this attribute.

      The Smart GWT server will automatically set this property whenever progressive loading is enabled. Developers may also set this property themselves for custom progressive loading implementations.

      Returns:
        Current progressiveLoading value. Default value is null

    - #### setQueueStatus

          public DSResponse setQueueStatus(int queueStatus)

      An extra property of each DSResponse to a queued request that indicates whether the queue as a whole succeeded. A queueStatus of `STATUS_SUCCESS`, or 0, indicates that the queue succeeded whereas a queueStatus of `STATUS_FAILURE`, or -1, indicates that the queue failed.

      For example, if two "update" requests are sent in a queue and the first succeeded, but the second failed validation, then both DSResponses' queueStatus would be -1, but the `status` of the first would be `STATUS_SUCCESS` and the status of the second would be an error code such as `STATUS_VALIDATION_ERROR`.

      Parameters:
        `queueStatus` - New queueStatus value. Default value is see below
      Returns:
        `DSResponse` instance, for chaining setter calls
      See Also:
        `ErrorHandling overview and related methods`

    - #### getQueueStatus

          public int getQueueStatus()

      An extra property of each DSResponse to a queued request that indicates whether the queue as a whole succeeded. A queueStatus of `STATUS_SUCCESS`, or 0, indicates that the queue succeeded whereas a queueStatus of `STATUS_FAILURE`, or -1, indicates that the queue failed.

      For example, if two "update" requests are sent in a queue and the first succeeded, but the second failed validation, then both DSResponses' queueStatus would be -1, but the `status` of the first would be `STATUS_SUCCESS` and the status of the second would be an error code such as `STATUS_VALIDATION_ERROR`.

      Returns:
        Current queueStatus value. Default value is see below
      See Also:
        `ErrorHandling overview and related methods`

    - #### getStartRow

          public java.lang.Integer getStartRow()

      Starting row of returned server results, when using paged result fetching

      Note that startRow and endRow are zero-based, inclusive at the beginning and exclusive at the end (like substring), so startRow: 0, endRow: 2 is a response containing two records.

      Returns:
        Current startRow value. Default value is null

    - #### setStatus

          public DSResponse setStatus(int status)
