## Class InnerJoin

- java.lang.Object
- - org.eclipse.rdf4j.sail.shacl.planNodes.InnerJoin

- All Implemented Interfaces:
    MultiStreamPlanNode, PlanNode

      public class InnerJoin
      extends Object
      implements MultiStreamPlanNode, PlanNode

  Author:
    Håvard Ottestad

    This inner join algorithm assumes the left iterator is unique for tuple[0], eg. no two tuples have the same value at index 0. The right iterator is allowed to contain duplicates.
