Examples of de.fuberlin.wiwiss.d2rq.find.FindQuery

de.fuberlin.wiwiss.d2rq.find.FindQuery
A find query on a collection of {@link TripleRelation}s. Results are delivered as a {@link QueryIter} over three-variable s/p/o bindings.Will combine queries on multiple relations into one SQL statement where possible. An option for limiting the number of triples returned from each {@link TripleRelation} is available. @author Richard Cyganiak (richard@cyganiak.de)
