Class ConjunctiveQuery

java.lang.Object

org.aksw.jena_sparql_api.algebra.utils.ConjunctiveQuery

public class ConjunctiveQuery
extends Object

Note: The reason why SparqlConjunctiveQuery and QuadFilterPatternCanonical are not the same object (i.e. we could make the projection part of the QFPC), is, that one QFPC may be indexed with different projections. Via OpConjunctiveQuery, conjunctive queries can be placed into SPARQL algebra expressions.
