|---|---|
| class  | DescribeOperator | 
| class  | Distinct | 
| class  | ExtensionAn extension operator that can be used to add bindings to solutions whose values are defined by  value expressions. | 
| class  | FilterThe FILTER operator, as defined in SPARQL Query
 Language for RDF. | 
| class  | GroupA tuple operator that groups tuples that have a specific set of equivalent variable bindings, and that can apply
 aggregate functions on the grouped results. | 
| class  | MultiProjectionA "multi-projection" that can produce multiple solutions from a single set of bindings. | 
| class  | OrderAn order operator that can be used to order bindings as specified by a set of value expressions. | 
| class  | ProjectionA generalized projection (allowing the bindings to be renamed) on a tuple expression. | 
| class  | QueryRootA semantics-less query model node that is used as the root of query model trees. | 
| class  | Reduced | 
| class  | ServiceThe SERVICE keyword as defined in SERVICE
 definition. | 
| class  | SliceThe SLICE operator, as defined in SPARQL Query
 Language for RDF. |
