    Subclasses of UnaryTupleOperator in org.eclipse.rdf4j.query.algebra
    Modifier and Type | Class | Description
    --- | --- | ---
    `class` | `DescribeOperator` |
    `class` | `Distinct` |
    `class` | `Extension` | An extension operator that can be used to add bindings to solutions whose values are defined by `value expressions`.
    `class` | `Filter` | The FILTER operator, as defined in SPARQL Query Language for RDF.
    `class` | `Group` | A 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` | `MultiProjection` | A "multi-projection" that can produce multiple solutions from a single set of bindings.
    `class` | `Order` | An order operator that can be used to order bindings as specified by a set of value expressions.
    `class` | `Projection` | A generalized projection (allowing the bindings to be renamed) on a tuple expression.
    `class` | `QueryRoot` | A semantics-less query model node that is used as the root of query model trees.
    `class` | `Reduced` |
    `class` | `Service` | The SERVICE keyword as defined in SERVICE definition.
