      public class RPCRequest
      extends RefDataClass

  Encapsulates a client/server RPC request. You'll need to provide an instance of this class (or a constructor for it) to the `RPCManager.sendRequest()` method. If you use the `RPCManager.send()` method, an instance of RPCRequest will be created for you.
  See Also:
    `RPCManager.send(java.lang.String, com.smartgwt.client.rpc.RPCCallback, com.smartgwt.client.rpc.RPCRequest)`, `RPCManager.sendRequest(com.smartgwt.client.rpc.RPCRequest)`

    Modifier and Type | Method and Description
    --- | ---
    `boolean` | `downloadCallback(RPCResponse response, java.util.Map data, java.lang.String fileName, java.lang.String type, RPCRequest request)` Callback for `download requests` with `transport` set to `"xmlHttpRequest"`.
    `java.lang.String` | `getActionURL()` Overrides RPCManager.actionURL for this request only.
    `java.lang.Boolean` | `getAllowIE9Leak()` Advanced flag to avoid a potential memory leak in Internet Explorer 9 for requests with JSON formatted responses.

    `java.lang.String` | `getCallbackParam()` For use only with the `scriptInclude` transport, this attribute specifies the name of the URL parameter which is used to specify the callback function that the server is expected to call by writing out JavaScript code.
    `java.lang.Boolean` | `getContainsCredentials()` For use during `Relogin`, this property marks this request an attempt to login, therefore a response containing the `loginRequiredMarker` is a normal condition and should result in the status code `STATUS_LOGIN_INCORRECT` rather than a call to `loginRequired()`.
    `java.lang.String` | `getContentType()` Valid with the xmlHttpRequest transport only and only when `httpMethod` is set to "POST".
    `com.google.gwt.core.client.JavaScriptObject` | `getData()` Returns the payload of this request to be sent to the server, as a JavaScriptObject.
    `java.lang.String` | `getDataAsString()`
    `java.lang.Boolean` | `getDownloadResult()` If enabled, causes the RPCRequest to download the requested resource as a file, either showing the browser's Save dialog or displaying the file-content in `a new browser window`.
    `java.lang.Boolean` | `getDownloadToNewWindow()` When `downloadResult` is true, setting this attribute to true causes the content of the downloaded file to be displayed in a new browser window.
    `java.lang.Boolean` | `getEvalResult()` This works similarly to `serverOutputAsString` except the resulting String is automatically evaluated as JavaScript.

    `java.lang.Boolean` | `getShowPrompt()` Overrides `RPCManager.showPrompt` for this request only.
    `java.lang.Boolean` | `getSuppressAutoDraw()` If `evalResult` is set, setting this property to true causes `Canvas.autoDraw` to be set to false for the duration of the result evaluation - which is generally what you want if you're returning new components from the server.

    - #### getOrCreateRef

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

    - #### setActionURL

          public RPCRequest setActionURL(java.lang.String actionURL)

      Overrides RPCManager.actionURL for this request only. If you're using queuing, note that queues as per-URL - in other words all RPCRequests in a queue must go to a single URL. If you attempt to send a request with an actionURL that is different from those already in the queue, it will be sent to the server separately, ahead of the queue, and a warning will be logged to the Developer Console.
      Parameters:
        `actionURL` - New actionURL value. Default value is RPCManager.actionURL
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `com.smartgwt.client.rpc.RPCManager#actionURL`, `URL`

    - #### getActionURL

          public java.lang.String getActionURL()

      Overrides RPCManager.actionURL for this request only. If you're using queuing, note that queues as per-URL - in other words all RPCRequests in a queue must go to a single URL. If you attempt to send a request with an actionURL that is different from those already in the queue, it will be sent to the server separately, ahead of the queue, and a warning will be logged to the Developer Console.
      Returns:
        Current actionURL value. Default value is RPCManager.actionURL
      See Also:
        `com.smartgwt.client.rpc.RPCManager#actionURL`, `URL`

    - #### setAllowIE9Leak

          public RPCRequest setAllowIE9Leak(java.lang.Boolean allowIE9Leak)

      Advanced flag to avoid a potential memory leak in Internet Explorer 9 for requests with JSON formatted responses.

      This attribute may be set to `false` to explicitly enable the workaround described `here` for this request, avoiding a potential memory leak in Internet Explorer 9.

      This workaround has a limitation in that if parsing the JSON response generates certain object types including JavaScript `Date` or `function` objects, attempts to interact with these objects can subsequently lead to a JavaScript error with the message `"Can't execute code from a freed script"`.

      This workaround therefore may not be suitable for all transactions or dataSources within a given application.

      This property may also be set globally within an application (via `allowIE9Leak`)_.

      Note: This memory leak and workaround is discussed further in the online Smart GWT FAQ.

      Note : This is an advanced setting

      Parameters:
        `allowIE9Leak` - New allowIE9Leak value. Default value is null
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getAllowIE9Leak

          public java.lang.Boolean getAllowIE9Leak()

      Advanced flag to avoid a potential memory leak in Internet Explorer 9 for requests with JSON formatted responses.

      This attribute may be set to `false` to explicitly enable the workaround described `here` for this request, avoiding a potential memory leak in Internet Explorer 9.

      This workaround has a limitation in that if parsing the JSON response generates certain object types including JavaScript `Date` or `function` objects, attempts to interact with these objects can subsequently lead to a JavaScript error with the message `"Can't execute code from a freed script"`.

      This workaround therefore may not be suitable for all transactions or dataSources within a given application.

      This property may also be set globally within an application (via `allowIE9Leak`)_.

      Note: This memory leak and workaround is discussed further in the online Smart GWT FAQ.

      Returns:
        Current allowIE9Leak value. Default value is null

    - #### setBypassCache

          public RPCRequest setBypassCache(java.lang.Boolean bypassCache)

      For xmlHttp transport + httpMethod: "GET" only, set to true to force a conditional GET request even if the browser thinks it has a current cached response.

      Note : This is an advanced setting

      Parameters:
        `bypassCache` - New bypassCache value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getBypassCache

          public java.lang.Boolean getBypassCache()

      For xmlHttp transport + httpMethod: "GET" only, set to true to force a conditional GET request even if the browser thinks it has a current cached response.
      Returns:
        Current bypassCache value. Default value is false

    - #### setCallbackParam

          public RPCRequest setCallbackParam(java.lang.String callbackParam)

      For use only with the `scriptInclude` transport, this attribute specifies the name of the URL parameter which is used to specify the callback function that the server is expected to call by writing out JavaScript code. The actual function to call is automatically generated and differs for every request (to allow concurrency).

      For example, with `callbackParam` set to it's default value of "callback", the server might be contacted with a URL like:

               loadData?callback=isc_scriptIncludeCallback_5

      .. then the server's response should look like:

               isc_scriptIncludeCallback_5({ .. data .. });

      The name "isc_scriptIncludeCallback_5" is automatically generated and will differ each time the server is contacted.

      Smart GWT makes of this server-provided callback mechanism, then calls `callback` normally.

      `rpcRequest.callbackParam` is ignored by all transport other than `scriptInclude`.

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

    - #### getCallbackParam

          public java.lang.String getCallbackParam()

      For use only with the `scriptInclude` transport, this attribute specifies the name of the URL parameter which is used to specify the callback function that the server is expected to call by writing out JavaScript code. The actual function to call is automatically generated and differs for every request (to allow concurrency).

      For example, with `callbackParam` set to it's default value of "callback", the server might be contacted with a URL like:

               loadData?callback=isc_scriptIncludeCallback_5

      .. then the server's response should look like:

               isc_scriptIncludeCallback_5({ .. data .. });

      The name "isc_scriptIncludeCallback_5" is automatically generated and will differ each time the server is contacted.

      Smart GWT makes of this server-provided callback mechanism, then calls `callback` normally.

      `rpcRequest.callbackParam` is ignored by all transport other than `scriptInclude`.

      Returns:
        Current callbackParam value. Default value is "callback"

    - #### setContainsCredentials

          public RPCRequest setContainsCredentials(java.lang.Boolean containsCredentials)

      For use during `Relogin`, this property marks this request an attempt to login, therefore a response containing the `loginRequiredMarker` is a normal condition and should result in the status code `STATUS_LOGIN_INCORRECT` rather than a call to `loginRequired()`.

      It is not required to set `containsCredentials`, however, it does typically simplify relogin logic by separating the handling of RPCs that are login attempts from RPCs that are not.

      Note : This is an advanced setting

      Parameters:
        `containsCredentials` - New containsCredentials value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `Relogin`

    - #### getContainsCredentials

          public java.lang.Boolean getContainsCredentials()

      For use during `Relogin`, this property marks this request an attempt to login, therefore a response containing the `loginRequiredMarker` is a normal condition and should result in the status code `STATUS_LOGIN_INCORRECT` rather than a call to `loginRequired()`.

      It is not required to set `containsCredentials`, however, it does typically simplify relogin logic by separating the handling of RPCs that are login attempts from RPCs that are not.

      Returns:
        Current containsCredentials value. Default value is false
      See Also:
        `Relogin`

    - #### setContentType

          public RPCRequest setContentType(java.lang.String contentType)

      Valid with the xmlHttpRequest transport only and only when `httpMethod` is set to "POST".
      Parameters:
        `contentType` - New contentType value. Default value is "application/x-www-form-urlencoded"
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getContentType

          public java.lang.String getContentType()

      Valid with the xmlHttpRequest transport only and only when `httpMethod` is set to "POST".
      Returns:
        Current contentType value. Default value is "application/x-www-form-urlencoded"

    - #### setData

          public RPCRequest setData(java.lang.String data)

      This attribute specifies the payload of the RPCRequest. When using the `Smart GWT server`, objects sent to the server as `request.data` will be available on the server-side `RPCRequest` object as Java Objects. This is achieved by serializing the client side data in a JSON type format and generating Java Objects on the server from this serialized data.

      If the client side `request.data` is set to a Java object in your SmartGWT code it will be serialized as JSON as follows:
      - Numeric client side values (int, Integer, etc) will be serialized as JavaScript numbers.
      - String values will be serialized as JavaScript strings.
      - Date values will be serialized as JavaScript dates.
      - Maps or Record objects will be serialized as JavaScript Objects.
      - Arrays or Lists will become JavaScript arrays
      Serialization of Maps and Arrays is recursive - each entry in an Array, or attribute on a Map will also be serialized according to the above rules.
      Note that you can also set `request.data` directly to a JavaScriptObject, and use the `JSOHelper` class or `SomeObject.getJSObj()` to perform your own data conversions on the client. The serialized JavaScript will then be converted back to Java on the server according to the following rules.

      Here are the mapping of JavaScript types to their corresponding server object types:

      JS Type | Java Type
      Object: {} | Map
      Array: [] | List
      String | String
      Number | Long|Double
      Boolean | Boolean
      Date | java.util.Date
      String | com.smartgwt.client.types.ValueEnum

      Note that the order of keys/values in the Maps created on the server is not guaranteed because JavaScript Object literals do not guarantee order.

      When using JPA or Hibernate Java value used can be affected by the Java Bean declaration. See `DsRequestBeanTypes` for details.

      Server->client conversion follows this table as well, with some extras. See the toJS() method on JSTranslater in the server documentation for a description of additional behaviors.

      When not communicating with the Smart GWT server, `rpcRequest.data` becomes simple HTTP parameters or an HTTP request body - see `useSimpleHttp` for details.

      Parameters:
        `data` - New data value. Default value is null
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `com.smartgwt.client.rpc.RPCResponse#setData`

    - #### setData

          public RPCRequest setData(Record data)

      This attribute specifies the payload of the RPCRequest. When using the `Smart GWT server`, objects sent to the server as `request.data` will be available on the server-side `RPCRequest` object as Java Objects. This is achieved by serializing the client side data in a JSON type format and generating Java Objects on the server from this serialized data.

      If the client side `request.data` is set to a Java object in your SmartGWT code it will be serialized as JSON as follows:
      - Numeric client side values (int, Integer, etc) will be serialized as JavaScript numbers.
      - String values will be serialized as JavaScript strings.
      - Date values will be serialized as JavaScript dates.
      - Maps or Record objects will be serialized as JavaScript Objects.
      - Arrays or Lists will become JavaScript arrays
      Serialization of Maps and Arrays is recursive - each entry in an Array, or attribute on a Map will also be serialized according to the above rules.
      Note that you can also set `request.data` directly to a JavaScriptObject, and use the `JSOHelper` class or `SomeObject.getJSObj()` to perform your own data conversions on the client. The serialized JavaScript will then be converted back to Java on the server according to the following rules.

      Here are the mapping of JavaScript types to their corresponding server object types:

      JS Type | Java Type
      Object: {} | Map
      Array: [] | List
      String | String
      Number | Long|Double
      Boolean | Boolean
      Date | java.util.Date
      String | com.smartgwt.client.types.ValueEnum

      Note that the order of keys/values in the Maps created on the server is not guaranteed because JavaScript Object literals do not guarantee order.

      When using JPA or Hibernate Java value used can be affected by the Java Bean declaration. See `DsRequestBeanTypes` for details.

      Server->client conversion follows this table as well, with some extras. See the toJS() method on JSTranslater in the server documentation for a description of additional behaviors.

      When not communicating with the Smart GWT server, `rpcRequest.data` becomes simple HTTP parameters or an HTTP request body - see `useSimpleHttp` for details.

      Parameters:
        `data` - New data value. Default value is null
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `com.smartgwt.client.rpc.RPCResponse#setData`

    - #### setData

          public RPCRequest setData(java.util.Map data)

      This attribute specifies the payload of the RPCRequest. When using the `Smart GWT server`, objects sent to the server as `request.data` will be available on the server-side `RPCRequest` object as Java Objects. This is achieved by serializing the client side data in a JSON type format and generating Java Objects on the server from this serialized data.

      If the client side `request.data` is set to a Java object in your SmartGWT code it will be serialized as JSON as follows:
      - Numeric client side values (int, Integer, etc) will be serialized as JavaScript numbers.
      - String values will be serialized as JavaScript strings.
      - Date values will be serialized as JavaScript dates.
      - Maps or Record objects will be serialized as JavaScript Objects.
      - Arrays or Lists will become JavaScript arrays
      Serialization of Maps and Arrays is recursive - each entry in an Array, or attribute on a Map will also be serialized according to the above rules.
      Note that you can also set `request.data` directly to a JavaScriptObject, and use the `JSOHelper` class or `SomeObject.getJSObj()` to perform your own data conversions on the client. The serialized JavaScript will then be converted back to Java on the server according to the following rules.

      Here are the mapping of JavaScript types to their corresponding server object types:

      JS Type | Java Type
      Object: {} | Map
      Array: [] | List
      String | String
      Number | Long|Double
      Boolean | Boolean
      Date | java.util.Date
      String | com.smartgwt.client.types.ValueEnum

      Note that the order of keys/values in the Maps created on the server is not guaranteed because JavaScript Object literals do not guarantee order.

      Server->client conversion follows this table as well, with some extras. See the toJS() method on JSTranslater in the server documentation for a description of additional behaviors.

      When not communicating with the Smart GWT server, `rpcRequest.data` becomes simple HTTP parameters or an HTTP request body - see `useSimpleHttp` for details.

      Parameters:
        `data` - New data value. Default value is null
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `com.smartgwt.client.rpc.RPCResponse#setData`

    - #### setDownloadResult

          public RPCRequest setDownloadResult(java.lang.Boolean downloadResult)

      If enabled, causes the RPCRequest to download the requested resource as a file, either showing the browser's Save dialog or displaying the file-content in `a new browser window`.

      Download requests will use `transport`: "hiddenFrame" by default.

      In this mode, the download will be performed by a standard HTTP request issued by the browser. If `DSRequest.downloadToNewWindow` is true, the request will be targeted against a new browser window, and if the resulting file can be displayed inline by the browser it will be. If `DSRequest.downloadToNewWindow` is not true, or the browser cannot display the returned file inline, the browser will download the file and store it to the user's file system.

      Download requests with `transport`: "hiddenFrame" do not fire any callbacks.

      If a developer explicitly sets `request.transport` to "xmlHttpRequest", the browser will instead use an XMLHttpRequest to download the data from the server. This mode differs from hiddenFrame downloads in various ways:

      - Explicit `httpHeaders` may be sent to the server in this mode
      - Instead of automatically downloading the response to the user's filesystem, the server response will be available as a Blob, and the `downloadCallback()` will be invoked, if specified.
        Returning `false` from the downloadCallback will suppress the default behavior of saving the file to the user's filesystem, giving developers an opportunity to take other actions, such as generating a data URL from the Blob.
      - xmlHttpRequest download does not have a built-in progress bar to indicate download progress. Developers may make use of the `xhr_onProgress()` event to indicate download progress if required.

      Note : This is an advanced setting

      Parameters:
        `downloadResult` - New downloadResult value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getDownloadResult

          public java.lang.Boolean getDownloadResult()

      If enabled, causes the RPCRequest to download the requested resource as a file, either showing the browser's Save dialog or displaying the file-content in `a new browser window`.

      Download requests will use `transport`: "hiddenFrame" by default.

      In this mode, the download will be performed by a standard HTTP request issued by the browser. If `DSRequest.downloadToNewWindow` is true, the request will be targeted against a new browser window, and if the resulting file can be displayed inline by the browser it will be. If `DSRequest.downloadToNewWindow` is not true, or the browser cannot display the returned file inline, the browser will download the file and store it to the user's file system.

      Download requests with `transport`: "hiddenFrame" do not fire any callbacks.

      If a developer explicitly sets `request.transport` to "xmlHttpRequest", the browser will instead use an XMLHttpRequest to download the data from the server. This mode differs from hiddenFrame downloads in various ways:

      - Explicit `httpHeaders` may be sent to the server in this mode
      - Instead of automatically downloading the response to the user's filesystem, the server response will be available as a Blob, and the `downloadCallback()` will be invoked, if specified.
        Returning `false` from the downloadCallback will suppress the default behavior of saving the file to the user's filesystem, giving developers an opportunity to take other actions, such as generating a data URL from the Blob.
      - xmlHttpRequest download does not have a built-in progress bar to indicate download progress. Developers may make use of the `xhr_onProgress()` event to indicate download progress if required.
      Returns:
        Current downloadResult value. Default value is false

    - #### setDownloadToNewWindow

          public RPCRequest setDownloadToNewWindow(java.lang.Boolean downloadToNewWindow)

      When `downloadResult` is true, setting this attribute to true causes the content of the downloaded file to be displayed in a new browser window.

      Note that this setting is currently incompatible with `transport:"xmlHttpRequest"`. See the `downloadResult` documentation for more details on xmlHttpRequest downloads

      Note : This is an advanced setting

      Parameters:
        `downloadToNewWindow` - New downloadToNewWindow value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getDownloadToNewWindow

          public java.lang.Boolean getDownloadToNewWindow()

      When `downloadResult` is true, setting this attribute to true causes the content of the downloaded file to be displayed in a new browser window.

      Note that this setting is currently incompatible with `transport:"xmlHttpRequest"`. See the `downloadResult` documentation for more details on xmlHttpRequest downloads

      Returns:
        Current downloadToNewWindow value. Default value is false

    - #### setEvalResult

          public RPCRequest setEvalResult(java.lang.Boolean evalResult)

      This works similarly to `serverOutputAsString` except the resulting String is automatically evaluated as JavaScript. The result of the evaluation is then passed to any specified `callback` as `RPCResponse.data`.

      This feature can be used to dynamically load new application modules into a running application. An RPCRequest with `evalResult` enabled can be used to fetch a static .js file or JavaScript dynamically generated by the server. The returned JavaScript can contain anything that a JavaScript file loaded at init time can contain, including new views and new Smart GWT class definitions.

      Example usage with `RPCManager.sendRequest()`:

                 RPCRequest rpcRequestProperties = new RPCRequest();
                 rpcRequestProperties.setEvalResult(true);
                 rpcRequestProperties.setActionURL("js/loadLabel.js");
                 Map evalVars = new HashMap();
                 evalVars.put(var1, "A Value");
                 rpcRequestProperties.setEvalVars(evalVars);
                 RPCManager.sendRequest(rpcRequestProperties);

      This call would execute the code from `loadLabel.js`, and make the variable `var1` available to that code. Therefore if the .js file contained this code:

                 Label label = new Label();
                 label.setContents(var1);

      A label would be created with contents set to the value of `var1` - the string `"A Value"`.

      This feature relies on the XMLHttpRequest object which can be disabled by end-users in some supported browsers. See `PlatformDependencies` for more information.

      Note : This is an advanced setting

      Parameters:
        `evalResult` - New evalResult value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `ViewLoader`, `setEvalVars(java.util.Map)`

    - #### getEvalResult

                 rpcRequestProperties.setActionURL("js/loadLabel.js");
                 Map evalVars = new HashMap();
                 evalVars.put(var1, "A Value");
                 rpcRequestProperties.setEvalVars(evalVars);
                 RPCManager.sendRequest(rpcRequestProperties);

      This call would execute the code from `loadLabel.js`, and make the variable `var1` available to that code. Therefore if the .js file contained this code:

                 Label label = new Label();
                 label.setContents(var1);

      This feature relies on the XMLHttpRequest object which can be disabled by end-users in some supported browsers. See `PlatformDependencies` for more information.

      Returns:
        Current evalResult value. Default value is false

        `ViewLoader`, `com.smartgwt.client.rpc.RPCRequest#getEvalVars`

    - #### setEvalVars

          public RPCRequest setEvalVars(java.util.Map evalVars)

      If you've set `evalResult` : true, then the property values of this object will be available in the evaluation scope of the result under the variable names specified by the property names.

      So e.g. if evalVars is: `{foo: "bar"}` then a reference to the variable `foo` in the result will evaluate to `"bar"`.

      Note : This is an advanced setting

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

    - #### setHttpHeaders

    - #### setHttpMethod

          public RPCRequest setHttpMethod(java.lang.String httpMethod)

      Selects the HTTP method that will be used for the request. Typical values are "POST" and "GET".

      The more obscure "PUT", "DELETE" and "HEAD" methods are also valid, however, none of these are supported by the Safari browser previous to version 3.0.

      Parameters:
        `httpMethod` - New httpMethod value. Default value is "POST"
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getHttpMethod

          public java.lang.String getHttpMethod()

      Selects the HTTP method that will be used for the request. Typical values are "POST" and "GET".

      The more obscure "PUT", "DELETE" and "HEAD" methods are also valid, however, none of these are supported by the Safari browser previous to version 3.0.

      See Also:
        `com.smartgwt.client.rpc.RPCManager#httpProxyURL`

    - #### setIgnoreTimeout

          public RPCRequest setIgnoreTimeout(java.lang.Boolean ignoreTimeout)

      When set to true, no reply is expected from the server. However, if a reply is received, it will be processed.

      Note: setting this to true, forces `sendNoQueue` to `true` for this request.

      Note : This is an advanced setting

      Parameters:
        `ignoreTimeout` - New ignoreTimeout value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getIgnoreTimeout

      Returns:
        Current ignoreTimeout value. Default value is false

    - #### setIsBackgroundRequest

          public RPCRequest setIsBackgroundRequest(java.lang.Boolean isBackgroundRequest)

      Is this a background request?

      This attribute may be set to true for requests that do not interfere with the normal flow of user interaction within an application.

      Background requests are ignored by `AutoTest.waitForSystemDone()`, giving automated testing tools a way to identify specific operations that should not interfere with the flow of the test, without entirely disabling the ability to `wait for network operations`.

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

    - #### getIsBackgroundRequest

          public java.lang.Boolean getIsBackgroundRequest()

      Is this a background request?

      This attribute may be set to true for requests that do not interfere with the normal flow of user interaction within an application.

      Background requests are ignored by `AutoTest.waitForSystemDone()`, giving automated testing tools a way to identify specific operations that should not interfere with the flow of the test, without entirely disabling the ability to `wait for network operations`.

      Returns:
        Current isBackgroundRequest value. Default value is null

    - #### setMockMode

          public RPCRequest setMockMode(java.lang.Boolean mockMode)

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

    - #### getMockMode

          public java.lang.Boolean getMockMode()

      If enabled and request is applied to `RPCManager.cacheScreens()` or `RPCManager.loadScreen()` indicates that referenced DataSources should be loaded in mock mode.
      Returns:
        Current mockMode value. Default value is null

    - #### setOmitNullMapValuesInResponse

          public RPCRequest setOmitNullMapValuesInResponse(java.lang.Boolean omitNullMapValuesInResponse)

      If enabled, the server omits any key/value pairs in map that have null values from the response. This can reduce the size of the response when many fields have null values.

      To enable this globally for all responses you can set RPCManager.omitNullMapValuesInResponse in `server.properties`.

      Note that `SQL DataSources` don't add nulls to results for null values so this flag does nothing in that case.

      Note : This is an advanced setting

      Parameters:
        `omitNullMapValuesInResponse` - New omitNullMapValuesInResponse value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getOmitNullMapValuesInResponse

          public java.lang.Boolean getOmitNullMapValuesInResponse()

      If enabled, the server omits any key/value pairs in map that have null values from the response. This can reduce the size of the response when many fields have null values.

      To enable this globally for all responses you can set RPCManager.omitNullMapValuesInResponse in `server.properties`.

      Note that `SQL DataSources` don't add nulls to results for null values so this flag does nothing in that case.

      Returns:
        Current omitNullMapValuesInResponse value. Default value is false

    - #### setParams

          public RPCRequest setParams(java.util.Map params)

      Values to be sent as simple HTTP params, as a JavaScript Object where each property/value pair will become an HTTP parameter name and value. These parameters are then accessible on the server, for example, using servletRequest.getParameter(paramName) in Java Servlets.

      Array-valued parameters will be submitted as multiple instances of the same parameter, similar to an HTML form with a multi-select (?paramName=value1&paramName=value2 ...), accessible as getParameterValues(paramName) in Java Servlets. Any non-atomic type, such as an Object, will be serialized to JSON by the `JSONEncoder`. If this isn't desirable, serialize the data in advance so that the value provided in `rpcRequest.params` is a String.

      Note that this API is primarily used in combination with `useSimpleHttp` - when contacting the Smart GWT Server, use `data` instead, which provides full JavaScript <-> Java translation of arbitrary structures. `rpcRequest.params` can also be used with the Smart GWT Server, where it provides an an opportunity to send additional data aside from the main `data` payload. This is useful for adding data to DataSource requests which will be kept separate from the automatically sent DataSource data, or for making parts of the request visible in the URL for HTTP-level logging or layer 4 switches.

      Note that in contrast to `data` object, the data in `rpcRequest.params` is not deserialized by the Smart GWT server, and all values arrive on the server as String type (like HTTP parameters always do).

      Note: The params are submitted once per http transaction. If you are using `request queuing` to bundle multiple RPCRequests or DSRequests into a single HTTP turnaround, the params from the various RPCRequests will be merged, with the later-queued transactions winning on parameter name collisions. A warning will be logged in the Developer Console if multiple RPCRequests specified params.

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

    - #### getParams

          public java.util.Map getParams()

      Values to be sent as simple HTTP params, as a JavaScript Object where each property/value pair will become an HTTP parameter name and value. These parameters are then accessible on the server, for example, using servletRequest.getParameter(paramName) in Java Servlets.

      Array-valued parameters will be submitted as multiple instances of the same parameter, similar to an HTML form with a multi-select (?paramName=value1&paramName=value2 ...), accessible as getParameterValues(paramName) in Java Servlets.

      Returns:
        Current params value. Default value is null

    - #### setPrompt

          public RPCRequest setPrompt(java.lang.String prompt)

    - #### setSendNoQueue

          public RPCRequest setSendNoQueue(java.lang.Boolean sendNoQueue)

      When set to true, this request is sent to the server immediately, bypassing any current queue.

      Note : This is an advanced setting

      Parameters:
        `sendNoQueue` - New sendNoQueue value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getSendNoQueue

          public java.lang.Boolean getSendNoQueue()

      When set to true, this request is sent to the server immediately, bypassing any current queue.
      Returns:
        Current sendNoQueue value. Default value is false

    - #### setServerOutputAsString

          public RPCRequest setServerOutputAsString(java.lang.Boolean serverOutputAsString)

      Setting this flag makes the body of the HTTP response available as a String in the `callback` as `RPCResponse.data`. This is typically only useful if you are sending a request that will not be received by the Smart GWT Java Server, however in that case, set `useSimpleHttp`:true instead, which implies `serverOutputAsString:true`.

      `serverOutputAsString:true` allows you to, for example, load the contents of static files off your webserver into a string for processing on the client with no server support. The `actionURL` must be in the same domain as the current page for this to work.

      This feature relies on the XMLHttpRequest object which can be disabled by end-users in some supported browsers. See `PlatformDependencies` for more information.

      Generally this API is used for either `non-Java backends` or for advanced usage such as content that requires processing before it can be used in Smart GWT components (such as client-side web scraping). Note that Smart GWT provides higher-level APIs for loading common types of data, see eg `HTMLFlow` for HTML content, `ViewLoader` for loading Smart GWT components, `XMLTools.loadXML()` for loading XML, `evalResult` for loading JSON, and `DataSource` for loading structured data in various formats.

      Note : This is an advanced setting

      Parameters:
        `serverOutputAsString` - New serverOutputAsString value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getServerOutputAsString

          public java.lang.Boolean getServerOutputAsString()

      Setting this flag makes the body of the HTTP response available as a String in the `callback` as `RPCResponse.data`. This is typically only useful if you are sending a request that will not be received by the Smart GWT Java Server, however in that case, set `useSimpleHttp`:true instead, which implies `serverOutputAsString:true`.

      `serverOutputAsString:true` allows you to, for example, load the contents of static files off your webserver into a string for processing on the client with no server support. The `actionURL` must be in the same domain as the current page for this to work.

      Returns:
        Current serverOutputAsString value. Default value is false

    - #### setShowPrompt

          public RPCRequest setShowPrompt(java.lang.Boolean showPrompt)

      Overrides `RPCManager.showPrompt` for this request only.

      If you're using queuing, note that if any of the requests in the queue specify showPrompt:true, then a prompt will be shown for the entire queue with the prompt text of the first request in the queue to specify a custom prompt if promptStyle is set to "dialog".

      If promptStyle is set to "cursor" for the request that specified showPrompt: true, then the entire queue uses the "cursor" style for the prompt.

      Parameters:
        `showPrompt` - New showPrompt value. Default value is null
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `com.smartgwt.client.rpc.RPCManager#showPrompt`, `setPromptStyle(com.smartgwt.client.types.PromptStyle)`, `RpcPrompt overview and related methods`

    - #### getShowPrompt

          public java.lang.Boolean getShowPrompt()

      Overrides `RPCManager.showPrompt` for this request only.

      If you're using queuing, note that if any of the requests in the queue specify showPrompt:true, then a prompt will be shown for the entire queue with the prompt text of the first request in the queue to specify a custom prompt if promptStyle is set to "dialog".

      If promptStyle is set to "cursor" for the request that specified showPrompt: true, then the entire queue uses the "cursor" style for the prompt.

      Returns:
        Current showPrompt value. Default value is null
      See Also:
        `com.smartgwt.client.rpc.RPCManager#showPrompt`, `getPromptStyle()`, `RpcPrompt overview and related methods`

    - #### setSuppressAutoDraw

          public RPCRequest setSuppressAutoDraw(java.lang.Boolean suppressAutoDraw)

      If `evalResult` is set, setting this property to true causes `Canvas.autoDraw` to be set to false for the duration of the result evaluation - which is generally what you want if you're returning new components from the server.

      This also effects components loaded via the `RPCManager.loadScreen()` API.

      Note : This is an advanced setting

      Parameters:
        `suppressAutoDraw` - New suppressAutoDraw value. Default value is true
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getSuppressAutoDraw

          public java.lang.Boolean getSuppressAutoDraw()

      If `evalResult` is set, setting this property to true causes `Canvas.autoDraw` to be set to false for the duration of the result evaluation - which is generally what you want if you're returning new components from the server.

      This also effects components loaded via the `RPCManager.loadScreen()` API.

      Returns:
        Current suppressAutoDraw value. Default value is true

    - #### setTimeout

          public RPCRequest setTimeout(java.lang.Integer timeout)

      Sets the timeout on this request. Default is to use `defaultTimeout`.

      If you're using `queuing`, note that the timeout setting derived from the last request in the queue is used for the entire queue. If you want to override the timeout for the queue, make sure to set your override at least on the last request in the queue.

      For the "xmlHttpRequest" `transport`, this timeout can only happen if the server actually fails to respond within the specified number of milliseconds. For the "hiddenFrame" transport, this timeout will occur for non-200 (HTTP_OK) responses.

      If `timeout` is set to zero, the RPCManager will not enforce a timeout for this request. However, note that all browsers enforce their own timeouts on HTTP requests, and may have different timeouts for different kinds of failures (no response at all from server, hung response after receiving headers, hung response after receiving partial data, etc). Also, intervening web proxies or firewalls may impose timeouts of their own.

      As a rough rule of thumb, if your server response will have a lengthy pause before data begins to be sent, 1-2 minutes is the maximum allowable pause for a public site and still may not work for a minority of users, but up to 4 minutes may be allowable in a controlled environment (intranet or extranet with well-known user base).

      Above these limits, your code should return some kind of immediate response to the browser, then kick off a server-side process to complete processing. The browser can then either poll for completion, or use a server-push notification system such as Smart GWT Real-Time Messaging (see http://smartclient.com/product).

      Note : This is an advanced setting

      Parameters:
        `timeout` - New timeout value. Default value is null
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `com.smartgwt.client.rpc.RPCManager#defaultTimeout`

    - #### getTimeout

          public java.lang.Integer getTimeout()

      Sets the timeout on this request. Default is to use `defaultTimeout`.

      If you're using `queuing`, note that the timeout setting derived from the last request in the queue is used for the entire queue. If you want to override the timeout for the queue, make sure to set your override at least on the last request in the queue.

      For the "xmlHttpRequest" `transport`, this timeout can only happen if the server actually fails to respond within the specified number of milliseconds. For the "hiddenFrame" transport, this timeout will occur for non-200 (HTTP_OK) responses.

        `com.smartgwt.client.rpc.RPCManager#defaultTimeout`

    - #### setTransport

          public RPCRequest setTransport(RPCTransport transport)

      Selects the transport used for this RPCRequest. If unset, the value of `defaultTransport` will be used.

      If you're using queueing, note that all requests in the queue must use the same transport. If you attempt to send a request via a different transport than those that are currently on the queue, it will be sent to the server separately, ahead of the queue, and a warning will be logged to the Developer Console.

      If you specify an unknown transport, an error will be logged to the DeveloperConsole and `defaultTransport` will be used instead.

      If you specify the `xmlHttpRequest` transport and it is not available, a warning will be logged to the Developer Console and the RPCManager will attempt to use the `hiddenFrame` transport instead for this request. Note that some features like `serverOutputAsString` require the `xmlHttpRequest` transport and will not work if the `xmlHttpRequest` transport is unavailable (this can happen if the end user is using Internet Explorer and has disabled ActiveX). You can check whether or not the `xmlHttpRequest` transport is currently available by calling `RPCManager.xmlHttpRequestAvailable()`.

      Note : This is an advanced setting

      Parameters:
        `transport` - New transport value. Default value is RPCManager.defaultTransport
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `com.smartgwt.client.rpc.RPCManager#defaultTransport`

    - #### getTransport

          public RPCTransport getTransport()

      Selects the transport used for this RPCRequest. If unset, the value of `defaultTransport` will be used.

      If you're using queueing, note that all requests in the queue must use the same transport. If you attempt to send a request via a different transport than those that are currently on the queue, it will be sent to the server separately, ahead of the queue, and a warning will be logged to the Developer Console.

      Returns:
        Current transport value. Default value is RPCManager.defaultTransport
      See Also:
        `com.smartgwt.client.rpc.RPCManager#defaultTransport`

    - #### setUseCursorTracker

          public RPCRequest setUseCursorTracker(boolean useCursorTracker)

      If true, an image is shown to the right of the cursor when `promptStyle` is set to "cursor", otherwise the cursor itself is modified via css to the value of `promptCursor`.

      If left unspecified, the default value is set by `useCursorTracker`.

      Parameters:
        `useCursorTracker` - New useCursorTracker value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `com.smartgwt.client.rpc.RPCManager#useCursorTracker`, `RpcPrompt overview and related methods`

    - #### getUseCursorTracker

          public boolean getUseCursorTracker()

      If true, an image is shown to the right of the cursor when `promptStyle` is set to "cursor", otherwise the cursor itself is modified via css to the value of `promptCursor`.

      If left unspecified, the default value is set by `useCursorTracker`.

      Returns:
        Current useCursorTracker value. Default value is false
      See Also:
        `com.smartgwt.client.rpc.RPCManager#useCursorTracker`, `RpcPrompt overview and related methods`

    - #### setUseHttpProxy

          public RPCRequest setUseHttpProxy(java.lang.Boolean useHttpProxy)

      Indicates whether this request should use the HttpProxyServlet in order to enable contacting hosts other than the origin server (available only in Pro Edition or better).

      When various UI components issues requests automatically, or when a call to `RPCManager.sendProxied()` is made, the HttpProxy will automatically be used for a URL that starts with "http" and uses a hostname other than "localhost" or `window.location.hostname`, or if the port number differs.

      `rpcRequest.useHttpProxy` should only be used to force requests to go through the HttpProxy when the above rules don't work, or to avoid using the HttpProxy when contacting hosts that allow cross-site calls via the Http Access Control standard.

      You can also set `useHttpProxy`:false to avoid ever using the HttpProxyServlet.

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

    - #### getUseHttpProxy

          public java.lang.Boolean getUseHttpProxy()

      Indicates whether this request should use the HttpProxyServlet in order to enable contacting hosts other than the origin server (available only in Pro Edition or better).

      When various UI components issues requests automatically, or when a call to `RPCManager.sendProxied()` is made, the HttpProxy will automatically be used for a URL that starts with "http" and uses a hostname other than "localhost" or `window.location.hostname`, or if the port number differs.

      `rpcRequest.useHttpProxy` should only be used to force requests to go through the HttpProxy when the above rules don't work, or to avoid using the HttpProxy when contacting hosts that allow cross-site calls via the Http Access Control standard.

      You can also set `useHttpProxy`:false to avoid ever using the HttpProxyServlet.

      Returns:
        Current useHttpProxy value. Default value is null

    - #### setUseSimpleHttp

          public RPCRequest setUseSimpleHttp(java.lang.Boolean useSimpleHttp)

      When set to true, assume the request is not going to the Smart GWT server, and hence send a simple HTTP request that does not use Smart GWT-specific request encoding.

      Values specified in `params` are sent to to the server as HTTP request parameters. If `httpMethod` is "GET", parameters appear in the request URL, otherwise if httpMethod is "POST", parameters are encoded in the request body (exactly like an HTML form does). These parameters are then accessible via typical server-side APIs for retrieving HTTP parameters, eg, servletRequest.getParameter(paramName) in Java Servlets.

      Note that if `httpMethod` method is POST and `data` is supplied, `data` is assumed to be a string to post as the HTTP request body, and `params` are sent as URL parameters instead. This usage is for sending custom request bodies such as the XML payloads used for SOAP. In this case, `contentType` is typically also set to indicate the content type of the request body.

      Setting `useSimpleHttp` to true also automatically sets `serverOutputAsString` to true as well.

      Note : This is an advanced setting

      Parameters:
        `useSimpleHttp` - New useSimpleHttp value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls

    - #### getUseSimpleHttp

          public java.lang.Boolean getUseSimpleHttp()

      When set to true, assume the request is not going to the Smart GWT server, and hence send a simple HTTP request that does not use Smart GWT-specific request encoding.

      Values specified in `params` are sent to to the server as HTTP request parameters. If `httpMethod` is "GET", parameters appear in the request URL, otherwise if httpMethod is "POST", parameters are encoded in the request body (exactly like an HTML form does). These parameters are then accessible via typical server-side APIs for retrieving HTTP parameters, eg, servletRequest.getParameter(paramName) in Java Servlets.

      Note that if `httpMethod` method is POST and `data` is supplied, `data` is assumed to be a string to post as the HTTP request body, and `params` are sent as URL parameters instead. This usage is for sending custom request bodies such as the XML payloads used for SOAP. In this case, `contentType` is typically also set to indicate the content type of the request body.

      Setting `useSimpleHttp` to true also automatically sets `serverOutputAsString` to true as well.

      Returns:
        Current useSimpleHttp value. Default value is false

    - #### setUseStrictJSON

          public RPCRequest setUseStrictJSON(java.lang.Boolean useStrictJSON)

      If set true, tells the server to use strict JSON format when serializing the response data. If set false, tells the server to use a more permissive encoding that is still valid JS, but is not technically valid JSON. The default value of null tells the server to use the default global setting (see below).

      To enable this globally for all responses you can set `RPCManager.useStrictJSON` in `server.properties`. If the global flag is not set either way in `server.properties`, it defaults to false.

      Note : This is an advanced setting

      Parameters:
        `useStrictJSON` - New useStrictJSON value. Default value is null
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `DSRequest.setUseStrictJSON(java.lang.Boolean)`

    - #### getUseStrictJSON

          public java.lang.Boolean getUseStrictJSON()

      If set true, tells the server to use strict JSON format when serializing the response data. If set false, tells the server to use a more permissive encoding that is still valid JS, but is not technically valid JSON. The default value of null tells the server to use the default global setting (see below).

      To enable this globally for all responses you can set `RPCManager.useStrictJSON` in `server.properties`. If the global flag is not set either way in `server.properties`, it defaults to false.

      Returns:
        Current useStrictJSON value. Default value is null
      See Also:
        `DSRequest.getUseStrictJSON()`

    - #### setWillHandleError

          public RPCRequest setWillHandleError(java.lang.Boolean willHandleError)

      With willHandleError:false, rpcResponses that indicate an error go through centralized handling in the RPCManager and rpcRequest.callback is never invoked.

      Setting willHandleError:true means that your rpcRequest.callback will receive rpcResponses that have an error status and must handle them.

      See also the error handling section in the `RPCManager` docs.

      Parameters:
        `willHandleError` - New willHandleError value. Default value is false
      Returns:
        `RPCRequest` instance, for chaining setter calls
      See Also:
        `RPCManager`, `Error Handling Overview`

    - #### getWillHandleError

          public java.lang.Boolean getWillHandleError()

      With willHandleError:false, rpcResponses that indicate an error go through centralized handling in the RPCManager and rpcRequest.callback is never invoked.

      Setting willHandleError:true means that your rpcRequest.callback will receive rpcResponses that have an error status and must handle them.

      See also the error handling section in the `RPCManager` docs.

      Returns:
        Current willHandleError value. Default value is false
      See Also:
        `RPCManager`, `Error Handling Overview`

    - #### setWithCredentials

          public RPCRequest setWithCredentials(java.lang.Boolean withCredentials)

      In browsers that support Cross-Origin Resource Sharing and XMLHttpRequest 2, and where the service at the `actionURL` allows the origin to send credentials (see `Access-Control-Allow-Credentials`), should user credentials such as cookies, HTTP authentication, and client-side SSL certificates be sent with the actual CORS request?

      This setting only applies when the request `transport` is `RPCTransport.XMLHTTPREQUEST`.

      Note that Internet Explorer 10 and 11 do not send cookies as part of user credentials: IE10 doesn't support cookies on cross origin XMLHttpRequest withCredentials=true.

      Note : This is an advanced setting

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

    - #### getWithCredentials

          public java.lang.Boolean getWithCredentials()

      In browsers that support Cross-Origin Resource Sharing and XMLHttpRequest 2, and where the service at the `actionURL` allows the origin to send credentials (see `Access-Control-Allow-Credentials`), should user credentials such as cookies, HTTP authentication, and client-side SSL certificates be sent with the actual CORS request?

      This setting only applies when the request `transport` is `RPCTransport.XMLHTTPREQUEST`.

      Note that Internet Explorer 10 and 11 do not send cookies as part of user credentials: IE10 doesn't support cookies on cross origin XMLHttpRequest withCredentials=true.

      Returns:
        Current withCredentials value. Default value is null

    - #### downloadCallback

          public boolean downloadCallback(RPCResponse response,
                                          java.util.Map data,
                                          java.lang.String fileName,
                                          java.lang.String type,
                                          RPCRequest request)

      Callback for `download requests` with `transport` set to `"xmlHttpRequest"`.

      This method will fire when a download request completes. If `DSRequest.willHandleError` is true it will fire on both successful completion or failure as reflected by the `DSResponse.status`.

      By default, successful download requests will save the returned file to the filesystem. To suppress this behavior, return false from this callback. This allows you to take some other action such as generating a data url to display media, etc.

      Note that for a successful download request, the `data` parameter will be a Blob. For an unsuccessful download attempt, the data parameter typically contains the error message from the server. To invoke standard error handling, `RPCManager.runDefaultErrorHandling()` may be called.

      Parameters:
        `response` - the response to the request
        `data` - The Blob returned by the server, or error message if the download was unsuccessful
        `fileName` - The file name for the downloaded file, derived from the content-disposition header.
        `type` - the content type for the downloaded file, as specified by the content-type header.
        `request` - the request that initiated the download
      Returns:
        return false to suppress default behavior of saving the download file to the user's filesystem.

    - #### xhr_onProgress

          public void xhr_onProgress(java.util.Map progressEvent,
                                     RPCRequest request)

      Progress event notification fired repeatedly during requests with `transport` set to `"xmlHttpRequest"`.

      This callback will be invoked from the native XMLHttpRequest progress event.

      This is typically useful to provide visual feedback to the user when a lengthy download is in progress.

      Parameters:
        `progressEvent` - The native ProgressEvent with attributes indicating the `loaded` content so far, and, if `Content-Length` headers were set on the response, the `total` download size. Note that this is a native event produced by the browser and Smart GWT does not guarantee consistency for the event object, or the timing of the `onprogress` event notifications across browsers.
        `request` - the request that initiated the download

    - #### setData

          public void setData(com.google.gwt.core.client.JavaScriptObject data)

      This attribute specifies the payload of the RPCRequest. When using the `Smart GWT server`, objects sent to the server as `request.data` will be available on the server-side `RPCRequest` object as Java Objects. This is achieved by serializing the client side data in a JSON type format and generating Java Objects on the server from this serialized data.

      If the client side `request.data` is set to a Java object in your SmartGWT code on the client side, logic in your server side code will be passed the following equivalent objects:

      Client | Server Type
      boolean primitive or Boolean | Boolean
      Non-fractional numeric value (e.g: int, Integer, long, Long) | Long
      Fractional numeric value (e.g:float, Float, double, Double) | Double
      String | String
      Date | Date
      List, Set, Iterator | List
      Map | Map
      Record | Map
      RecordList | List of Map
      ResultSet | List of Map (containing only loaded rows if the ResultSet has a partial cache on the client)

      Note that the order of keys/values in the Maps created on the server is not guaranteed because JavaScript Object literals do not guarantee order.

      Server->client conversion follows this table as well, with some extras. See the toJS() method on JSTranslater in the server documentation for a description of additional behaviors.

      When not communicating with the Smart GWT server, `rpcRequest.data` becomes simple HTTP parameters or an HTTP request body - see `useSimpleHttp` for details.

      Parameters:
        `data` - data Default value is null

    - #### getData

          public com.google.gwt.core.client.JavaScriptObject getData()

      Returns the payload of this request to be sent to the server, as a JavaScriptObject.
