Class ResponseTransformer

java.lang.Object
  com.smartgwt.client.data.ResponseTransformer

public abstract class ResponseTransformer
extends Object

The ResponseTransformer provides the equivalent functionality of overriding DataSource.transformResponse(DSResponse, DSRequest, Object) } when instantiating a DataSource on the client. However when obtaining a DataSource instance from the server using DataSource.getDataSource(java.lang.String), transformResponse(DSResponse, DSRequest, Object) cannot be overridden and so the responseTransformer parameter can be passed to DataSource.getDataSource(java.lang.String) instead.

Method Detail

transformResponse

protected abstract void transformResponse(DSResponse response,
                                          DSRequest request,
                                          Object data)

See the docs for DataSource.transformResponse(DSResponse, DSRequest, Object)

Parameters:

response - the response

request - the request

data - the raw data parameter. The type of this object depends on the specified dataFormat. if the dataFormat is custom, this will be a String. Otherwise this will be a JavaScript object. If the dataFormat is "json", the JavaScriptObject will be the raw JSON object(s) returned by the web service. If dataFormat is XML the JavaScriptObject will be the raw XML document object. Note that the JSOHelper and XMLTools utility classes can be used to work with these raw objects.
