Class ExtendedEvaluationStrategy

java.lang.Object

org.eclipse.rdf4j.query.algebra.evaluation.impl.StrictEvaluationStrategy

org.eclipse.rdf4j.query.algebra.evaluation.impl.TupleFunctionEvaluationStrategy

org.eclipse.rdf4j.query.algebra.evaluation.impl.ExtendedEvaluationStrategy

All Implemented Interfaces:

EvaluationStrategy, FederatedServiceResolver, FederatedServiceResolverClient, UUIDable

public class ExtendedEvaluationStrategy
extends TupleFunctionEvaluationStrategy

SPARQL 1.1 extended query evaluation strategy. This strategy adds the use of virtual properties, as well as extended comparison and mathematical operators to the minimally-conforming StrictEvaluationStrategy.
