Example 1 with FrontsTriple

use of org.apache.jena.graph.FrontsTriple in project jena by apache.

the class WhereClauseTest method testAddGraph_frontsTriple.

@ContractTest
public void testAddGraph_frontsTriple() {
    final Node s = NodeFactory.createURI("s");
    final Node p = NodeFactory.createURI("p");
    final Node o = NodeFactory.createURI("o");
    FrontsTriple ft = new FrontsTriple() {

        @Override
        public Triple asTriple() {
            return new Triple(s, p, o);
        }
    };
    WhereClause<?> whereClause = getProducer().newInstance();
    AbstractQueryBuilder<?> builder = whereClause.addGraph("<g>", ft);
    Query query = builder.build();
    ElementPathBlock epb = new ElementPathBlock();
    ElementNamedGraph eng = new ElementNamedGraph(NodeFactory.createURI("g"), epb);
    epb.addTriplePath(new TriplePath(new Triple(s, p, o)));
    WhereValidator visitor = new WhereValidator(eng);
    query.getQueryPattern().visit(visitor);
    assertTrue(visitor.matching);
}
