public class ExtendedEvaluationStrategy
extends StrictEvaluationStrategy

Deprecated, for removal: This API element is subject to removal in a future version.

Use DefaultEvaluationStrategy instead.

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.
