setJavaScriptObject

public void setJavaScriptObject(com.google.gwt.core.client.JavaScriptObject jsObj)

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:

. See 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 Overview for details.

Parameters:

status - 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.

getHttpHeaders

public java.util.Map getHttpHeaders()

HTTP headers returned by the server, as a Map of Header name -> 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:

the http headers

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 Maps or Lists 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 JavaScriptObjects 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()
