Package org.eclipse.rdf4j.sail.shacl.ast.planNodes

Class InnerJoin

java.lang.Object

org.eclipse.rdf4j.sail.shacl.ast.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.
