Class BoundJoinVALUESConversionIteration
java.lang.Object
org.eclipse.rdf4j.common.iteration.AbstractCloseableIteration<T>
org.eclipse.rdf4j.common.iteration.ConvertingIteration<BindingSet,BindingSet>
org.eclipse.rdf4j.federated.evaluation.iterator.BoundJoinVALUESConversionIteration
- All Implemented Interfaces:
AutoCloseable,Iterator<BindingSet>,CloseableIteration<BindingSet>
Inserts original bindings into the result. This implementation is used for bound joins with VALUES clauses, see
SparqlFederationEvalStrategyWithValues.
