Class RequestTransformer

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

public abstract class RequestTransformer
extends Object

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