public class TransformPullOrdered extends TransformDirectiveOnTopLevelFieldToQueryBase
Adds 
@ordered
to a query operation if any of its direct children has that directive. If the directive is present on the query then the SPARQL query rewrite will include a global ORDER BY clause. This is needed when the target SPARQL engine does not preserve order of bindings especially for union, lateral and extend operations. This flag should not be used in production, instead the rewrite mode should be set on the graphql engine level. The flag exists to make it easy to try out the ordered rewrite.
