  - ### Constructor Detail

    - #### RPCResponse

          public RPCResponse()

    - #### RPCResponse

          public RPCResponse(com.google.gwt.core.client.JavaScriptObject jsObj)

  - ### Method Detail

    - #### getOrCreateRef

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

    - #### 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.

      Returns:
        Map

    - #### getHttpResponseCode

          public java.lang.Integer getHttpResponseCode()

      This attribute (available when using the the `xmlHttpRequest` transport) contains the HTTP response code sent by the server.

      Note that this is different from `status` - that attribute is used to indicate a status code for the RPC itself whereas httpResponseCode is the raw HTTP response code for the HTTP request that contained the RPCRequest.

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

      If you're using this attribute, you'll typically want to avoid the default error handling response of RPCManager. To do so, set `willHandleError` to `true`.

      Returns:
        Integer

    - #### getHttpResponseText

          public java.lang.String getHttpResponseText()

      The actual text of the HTTP response. Only available when the default `RPCTransport` "xmlHttpRequest" transport is in use,
      Returns:
        String

    - #### setStatus

          public void setStatus(int status)

      Status code for this response. Status codes less than zero are considered errors by the RPCManager, those greater than or equal to zero are considered successes. Please see the error handling section the `RPCManager docs` for more information on what the RPCManager does with the status code and how you can override this behavior.

      When using the Smart GWT server you can set the rpcResponse.status by calling the server-side method RPCResponse.setStatus().

      When not using the Smart GWT server, the RPCManager makes no assumptions about the structure of the response, so the status code just reflects the `httpResponseCode`: status will be `STATUS_TRANSPORT_ERROR` if an HTTP-level error occurred such as "500 server error". If you have a status code you need to transmit you can simply embed it in the response (as part of `data`) and interpret it from the callback.

      With or without the Smart GWT server, the `Relogin` status codes (such as `STATUS_LOGIN_REQUIRED`) are triggered whenever special markers, such as the loginRequiredMarker, appear in the body of the response. See the `Relogin\n Overview` for details.

      Parameters:
        `status` -

    - #### getStatus

          public int getStatus()

      Status code for this response. Status codes less than zero are considered errors by the RPCManager, those greater than or equal to zero are considered successes. Please see the error handling section the `RPCManager docs` for more information on what the RPCManager does with the status code and how you can override this behavior.

      Returns:
        int

    - #### getTransactionNum

          public java.lang.Integer getTransactionNum()

      ID of the transaction sent to the server via `RPCManager.sendQueue()` containing the `RPCRequest` associated with this response.
      Returns:
        Integer

    - #### create

          public static void create()

      RPCResponses shouldn't be created directly. Instances of this class are automatically created and optionally passed to you in the callback you specify as part of your `RPCRequest`.

    - #### getDataAsMap

          public java.util.Map getDataAsMap()

      The data sent by the server.

      When communicating with the SmartClient server, `rpcResponse.data` is the data passed to the server-side method `RPCResponse.setData()` by your Java code. This data is translated into JavaScript objects by the rules described under `rpcRequest.data` in the SmartClient Reference. Simple types (Numeric values, Strings, Dates, Booleans) will be available as their equivalent Java types in your client side GWT code. Complex objects (such as serialized `Map`s or `List`s from the server) will not be automatically translated back into Java on the client - they will arrive as `JavaScriptObject` instances. You can easily convert to the appropriate type yourself using the `JSOHelper` class. The `JSOHelper.convertToJava(JavaScriptObject, boolean)` method performs a recursive conversion of `JavaScriptObject`s returning a `List` (or array) for JavaScript arrays or a `Map` for simple JavaScript objects (key:value pairs).

      When not communicating with the SmartClient server `rpcResponse.data` contains the raw HTTP response body. See `rpcRequest.useSimpleHttp`, rpcRequest.serverOutputAsString, `rpcRequest.evalResult` in the SmartClient Reference for details.

      Returns:
        the data in the RPC response, as a Map
      See Also:
        `RPCRequest.setData(JavaScriptObject)`, `RPCRequest.setData(Map)`, `RPCRequest.setData(com.smartgwt.client.data.Record)`, `RPCRequest.setData(String)`

    - #### getDataAsString

          public java.lang.String getDataAsString()

      The data sent by the server.

      When communicating with the SmartClient server, `rpcResponse.data` is the data passed to the server-side method `RPCResponse.setData()` by your Java code. This data is translated into JavaScript objects by the rules described under `rpcRequest.data` in the SmartClient Reference.
