Examples of com.hp.hpl.jena.sparql.core.Quad.asTriple()

com.hp.hpl.jena.sparql.core.Quad.asTriple()
Get as a triple - useful because quads often come in blocks for the same graph

        public Triple next() {
            Quad q = iter.next() ;
            if ( graphNode != null && !q.getGraph().equals(graphNode) )
                throw new InternalError("ProjectQuadsToTriples: Quads from unexpected graph (expected=" + graphNode
                                        + ", got=" + q.getGraph() + ")") ;
            return q.asTriple() ;
        }


        @Override
        public void remove() {
            iter.remove() ;
