Returns the special root object at the top of an otherwise empty data graph. This call is used when the application wants to create a data graph from scratch, without having called executeQuery() to create a data graph.
The special root object has one multi-valued containment property, with a name of the application root type that was passed when the Relational DAS was constructed. The property can take values of only that type. The only thing that the application can usefully do with the root type is to call createDataObject() on it, passing the name of the application root type, in order to create a data object of their own application type.
Please see the Examples section in the general information about the Relational DAS for many examples of calling this method.
