## Class BulkedExternalInnerJoin

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

- All Implemented Interfaces:
    PlanNode

      public class BulkedExternalInnerJoin
      extends Object

  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.

    External means that this plan node can join the iterator from a plan node with an external source (Repository or SailConnection) based on a query or a predicate.
