Class ServiceJoinConversionIteration

java.lang.Object

org.eclipse.rdf4j.common.iteration.AbstractCloseableIteration<T>

org.eclipse.rdf4j.common.iteration.ConvertingIteration<org.eclipse.rdf4j.query.BindingSet,org.eclipse.rdf4j.query.BindingSet>

org.eclipse.rdf4j.repository.sparql.federation.ServiceJoinConversionIteration

All Implemented Interfaces:

AutoCloseable, Iterator<org.eclipse.rdf4j.query.BindingSet>, org.eclipse.rdf4j.common.iteration.CloseableIteration<org.eclipse.rdf4j.query.BindingSet>

public class ServiceJoinConversionIteration
extends org.eclipse.rdf4j.common.iteration.ConvertingIteration<org.eclipse.rdf4j.query.BindingSet,org.eclipse.rdf4j.query.BindingSet>

Inserts original bindings into the result, uses ?__rowIdx to resolve original bindings. See org.eclipse.rdf4j.query.algebra.evaluation.federation.ServiceJoinIterator and SPARQLFederatedService.
