Class BulkedExternalInnerJoin

java.lang.Object

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

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

All Implemented Interfaces:

PlanNode

public class BulkedExternalInnerJoin
extends AbstractBulkJoinPlanNode

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.
