public class DefaultEvaluationStrategy extends Object implements EvaluationStrategy, FederatedServiceResolverClient, UUIDable
Default SPARQL 1.1 Query Evaluation strategy, to evaluate oneTupleExpron the givenTripleSource, optionally using the givenDataset. The behaviour of this strategy can be modified by setting theQueryEvaluationMode, which determines if the SPARQL query is evaluated usingstrictcompliance orstandardcompliance.- Author:
