    - #### setAllowAdvancedCriteria

          public OperationBinding setAllowAdvancedCriteria(java.lang.Boolean allowAdvancedCriteria)

      This property indicates whether this operation supports AdvancedCriteria. This setting overrides `DataSource.allowAdvancedCriteria` for this operation only. See `DataSource.supportsAdvancedCriteria()` for further information.

      NOTE: If you specify this property in a DataSource descriptor (`.ds.xml` file), it is enforced on the server. This means that if you run a request containing AdvancedCriteria against an OperationBinding that advertises itself as `allowAdvancedCriteria:false`, it will be rejected.

      Note : This is an advanced setting

      Parameters:
        `allowAdvancedCriteria` - New allowAdvancedCriteria value. Default value is null
      Returns:
        `OperationBinding` instance, for chaining setter calls
      See Also:
        `DataSource.setAllowAdvancedCriteria(java.lang.Boolean)`

    - #### getAllowAdvancedCriteria

    - #### setCallbackParam

          public OperationBinding setCallbackParam(java.lang.String callbackParam)

      Applies only to dataFormat: "json". Specifies the name of the query parameter that tells your JSON service what function to call as part of the response for this operation.

      Typically set once for the DataSource as a whole via `DataSource.callbackParam`.

      Parameters:
        `callbackParam` - New callbackParam value. Default value is "callback"
      Returns:
        `OperationBinding` instance, for chaining setter calls

      Parameters:
        `dataFormat` - New dataFormat value. Default value is "iscServer"
      Returns:
        `OperationBinding` instance, for chaining setter calls
      See Also:
        `ClientDataIntegration overview and related methods`

    - #### getDataFormat

          public DSDataFormat getDataFormat()

      Format for response data for this operation.

      Typically set once for the DataSource as a whole via `DataSource.dataFormat`.

      Returns:
        Current dataFormat value. Default value is "iscServer"
      See Also:
        `ClientDataIntegration overview and related methods`

    - #### setDataProtocol

          public OperationBinding setDataProtocol(DSProtocol dataProtocol)

      Controls the format in which inputs are sent to the dataURL.

      When a DataSource operation such as fetchData() is invoked on this DataSource or a component bound to this DataSource, the data passed to the operation, if any, will be sent to the `dataURL`. The `dataProtocol` property controls the format in which the data is sent: SOAP message, HTTP GET or POST of parameters, etc.

      The `dataProtocol` property need not be set for a DataSource with a WebService ( `DataSource.serviceNamespace` is set), in this case, SOAP messaging is used by default.

      Developers may completely bypass the Smart GWT comm system by setting dataProtocol to `"clientCustom"`. In this case Smart GWT will not attempt to send any data to the server after calling `DataSource.transformRequest()`. Instead the developer is expected to implement `transformRequest()` such that it performs the necessary data action outside of Smart GWT, and then calls `DataSource.processResponse()`, passing in the `DSRequest.requestId` and an appropriate set of DSResponse properties to indicate the result of the action.

      NOTE: when `dataFormat` is "iscServer", `dataProtocol` is not consulted. Instead, Smart GWT uses a proprietary wire format to communicate with the Smart GWT server, and the server-side DSRequest and DSResponse objects should be used to access request data and form responses.

      Parameters:
        `dataProtocol` - New dataProtocol value. Default value is "getParams"
      Returns:
        `OperationBinding` instance, for chaining setter calls
      See Also:
        `DSProtocol`, `ClientDataIntegration overview and related methods`

    - #### getDataProtocol

          public DSProtocol getDataProtocol()

        Current dataProtocol value. Default value is "getParams"
      See Also:
        `DSProtocol`, `ClientDataIntegration overview and related methods`

    - #### setDataTransport

          public OperationBinding setDataTransport(RPCTransport dataTransport)

      Transport to use for this operation. Defaults to `DataSource.dataTransport`, which in turn defaults to `defaultTransport`. This would typically only be set to enable "scriptInclude" transport for contacting `JSON` web services hosted on servers other than the origin server.

      When using the "scriptInclude" transport, be sure to set `DataSource.callbackParam` or `callbackParam` to match the name of the query parameter name expected by your JSON service provider.

      Parameters:
        `dataTransport` - New dataTransport value. Default value is RPCManager.defaultTransport
      Returns:
        `OperationBinding` instance, for chaining setter calls
      See Also:
        `RPCTransport`, `DataSource.setCallbackParam(java.lang.String)`, `ClientDataIntegration overview and related methods`

    - #### getDataTransport

          public RPCTransport getDataTransport()

      Transport to use for this operation. Defaults to `DataSource.dataTransport`, which in turn defaults to `defaultTransport`. This would typically only be set to enable "scriptInclude" transport for contacting `JSON` web services hosted on servers other than the origin server.

      If exportFields is not provided, the exported output includes all visible fields from the DataSource (field.hidden=false), sorted in the order they're defined.

      Parameters:
        `exportFields` - New exportFields value. Default value is null
      Returns:
        `OperationBinding` instance, for chaining setter calls

      When set, causes the results of the DataSource Operation to be exported to a file, whose name and format are indicated by `exportFilename` and `exportAs` respectively. When no exportFilename is provided, the default is Results and the default value of exportAs is csv. Once the Operation completes, `DSRequest.exportDisplay` specifies whether the exported data will be downloaded to the file-system or displayed in a new window. The default value of exportDisplay is "download" which displays the Save As dialog. See `ExportDisplay` for more information.

      The export field-list can also be configured, see `DSRequest.exportFields`.

      You can also configure the style of line-breaks to use when generating the output. See `LineBreakStyle` for more information.

      As well as setting this and other properties on the `OperationBinding`, Exports can be initiated in two other ways. You can set properties on the dsRequest by passing requestProperties into `DataSource.exportData()`. Note that this method does not support exporting to JSON format (see this post for more detail). Additionally, custom server code may set export-related properties on the `DSResponse`.

    - #### setRecordXPath

          public OperationBinding setRecordXPath(java.lang.String recordXPath)

      For an XML or JSON DataSource, XPath expression used to retrieve the objects that will become DataSource records.

      For example, an "ItemSearch" web service might return a "Results" structure containing metadata along with the set of Items that one might want to display in a grid. An XPath expression like "/Results/Items" could be used to retrieve just the Items, which would then become DataSource records.

      For a JSON web service, the `recordXPath` is applied to the returned JSON data via `XMLTools.selectObjects()`. Only limited XPath syntax is allowed; see `selectObjects()` for details.

      For processing XML results, see `xmlNamespaces` for information on the namespaces that are available in this XPath expression. If you are contacting a WSDL web service, note that `recordName` is an alternative way to specify which records should be selected by their tagName or type, and this is usually simpler.

      To learn about XPath, try the following search: http://www.google.com/search?q=xpath+tutorial

      Parameters:
        `recordXPath` - New recordXPath value. Default value is null

    - #### setRequestProperties

          public OperationBinding setRequestProperties(DSRequest requestProperties)

      Additional properties to pass through to the `DSRequest` created for this operation. Note that these will be cumulative with and will override on a per-property basis any properties set via `DataSource.requestProperties`.

    - #### setResponseDataSchema

          public OperationBinding setResponseDataSchema(DataSource responseDataSchema)

      Optional schema describing how to extract DataSource records from the XML elements selected.

      Once a set of XML elements have been selected via `recordXPath` or `recordName`, those elements are normally transformed to JavaScript objects using the `fields` of the DataSource that owns the operationBinding. A `responseDataSchema` can be specified instead if the XML differs in some way between different DataSource operations, such that different values for `field.valueXPath` may be necessary to extract the same DataSource record from slightly different XML structures.

      Note : This is an advanced setting

      Parameters:
        `responseDataSchema` - New responseDataSchema value. Default value is null
      Returns:
        `OperationBinding` instance, for chaining setter calls
      See Also:
        `ClientDataIntegration overview and related methods`

    - #### getResponseDataSchema

          public DataSource getResponseDataSchema()

      Once a set of XML elements have been selected via `recordXPath` or `recordName`, those elements are normally transformed to JavaScript objects using the `fields` of the DataSource that owns the operationBinding. A `responseDataSchema` can be specified instead if the XML differs in some way between different DataSource operations, such that different values for `field.valueXPath` may be necessary to extract the same DataSource record from slightly different XML structures.

    - #### setSpoofResponses

          public OperationBinding setSpoofResponses(boolean spoofResponses)

      For a DataSource contacting a `WSDL web service`, setting this flag means the DataSource doesn't actually attempt to contact the server but generates a sample response instead, based on the XML Schema of the response message embedded in the WSDL.

      The spoofed response will include all complexType elements and will fill in appropriate values by type for all simpleType elements, although the spoofed data will not conform to all xs:restriction declarations (eg xs:pattern).

      Note that if your WSDL does not fully describe the response format (some WSDL services just have a placeholder <xs:any> element), Smart GWT can only produce a partial response. To use a hand-generated sample response, just save an XML file to disk and use the `dataURL` setting to point to it.

      Parameters:
        `spoofResponses` - New spoofResponses value. Default value is false
      Returns:
        `OperationBinding` instance, for chaining setter calls
      See Also:
        `ClientDataIntegration overview and related methods`

    - #### getSpoofResponses

          public boolean getSpoofResponses()

      For a DataSource contacting a `WSDL web service`, setting this flag means the DataSource doesn't actually attempt to contact the server but generates a sample response instead, based on the XML Schema of the response message embedded in the WSDL.

    - #### setUseFlatFields

          public OperationBinding setUseFlatFields(boolean useFlatFields)

      Setting `useFlatFields` on an operationBinding is equivalent to setting `DSRequest.useFlatFields` on all DataSource requests with the same `operationType` as this `operationBinding`.

      Typical usage is to combine operationBinding.useFlatFields with `searchForm.useFlatFields`, with the `SearchForm` bound to the `input message` of the web service operation set as `wsOperation`. This allows gratuitous nesting to be consistently bypassed in both the user presentation and in the actual XML messaging.

      Note that `useFlatFields` is not generally recommended for use with input messages where multiple simple type fields exist with the same name, however if used in this way, the first field to use a given name wins. "first" means the first field encountered in a depth first search. "wins" means only the first field will be available in data binding, and only the first field will be populated in the generated XML message.

      Parameters:
        `useFlatFields` - New useFlatFields value. Default value is false
      Returns:
        `OperationBinding` instance, for chaining setter calls
      See Also:
        `ClientDataIntegration overview and related methods`

    - #### setWsOperation

          public OperationBinding setWsOperation(java.lang.String wsOperation)

      Name of the web service operation that will be invoked in order to execute this DataSource operation.

      Valid only for a DataSource that has a WebService (`DataSource.serviceNamespace` is set). Otherwise, use `dataURL`.

      Setting `wsOperation` means that `DSRequest.data` will be serialized as the request message for the specified web service operation, with namespacing and soap encoding handled automatically. See `DataSource.transformRequest()` for how to customize what data is sent to the server.

      Parameters:
        `wsOperation` - New wsOperation value. Default value is null
      Returns:
        `OperationBinding` instance, for chaining setter calls

    - #### setXmlNamespaces

          public OperationBinding setXmlNamespaces(XmlNamespaces xmlNamespaces)

      Optional object declaring namespace prefixes for use in `recordXPath` and `DataSourceField.valueXPath` XPath expressions.

      `xmlNamespaces` should be specified as a mapping from namespace prefix to namespace URI, for example:

               xmlNamespaces : {
                   az : "http://webservices.amazon.com/AWSECommerceService/2005-03-23"
               }

      By default, all namespaces declared on the document element (outermost element of the response) are made available with the prefix used in the document itself.

      Then, for non-WSDL-described XML results, if there is a default namespace on the document element, it is made available with the special prefix "default".

      For results of WSDL-described operations, the prefix "service" means the service namespace, that is, the "targetNamespace" on the <definitions> element from the WSDL file. The prefix "schema" means the namespace of the outermost element in the output message for the current operation. "default" will be the schema namespace if there is one, otherwise the service namespace.
