Examples of PathLengthZero

        // If there is a fixed subject or object, then we should consider it during evaluation!
        allowedSubjects = this.getSetOfLiterals(subjectNode);
        allowedObjects = this.getSetOfLiterals(objectNode);
      }


      final PathLengthZero zeroOperator = new PathLengthZero(subject, object, allowedSubjects, allowedObjects);
      memoryScan.addSucceedingOperator(new OperatorIDTuple(zeroOperator,0));


      final Union union = new Union();
      zeroOperator.addSucceedingOperator(new OperatorIDTuple(union,0));
      startingOperator.addSucceedingOperator(new OperatorIDTuple(union,1));


      final InMemoryDistinct distinct = new InMemoryDistinct();
      union.addSucceedingOperator(new OperatorIDTuple(distinct,0));
