Class NonUniqueTargetLang

java.lang.Object

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

All Implemented Interfaces:

PlanNode

public class NonUniqueTargetLang
extends Object
implements PlanNode

This PlanNode takes a stream of Tuples like: (ex:companyA, "Company A"@en). It assumes that the stream is sorted on index 0 (eg. ex:CompanyA). It will cache all non-empty languages from index 1 (eg. "en") and outputs any tuples where the language has already been seen.

If a Value on index 1 has no language because it is a literal without a language or because it is an IRI or BNode, then its language is considered empty and not cached.
