> 1) model.listStatements(s,p,null,lang) doesn't filter on lang param
> 2) model.listStatements(s,p,o,null) only returns statements whose object has
> lang "" (when o != null)
> TEST 1
> import org.junit.Test;
> import com.hp.hpl.jena.rdf.model.*;
> public class LstStmt1 {
> @Test
> public final void test() {
> Model m = ModelFactory.createDefaultModel();
> Resource s = m.createResource("http://www.a.com/s";);
> Property p = m.createProperty("http://www.a.com/p";);
> m.add(s,p,m.createResource("http://www.a.com/o";));
> m.add(s,p,"texte","fr");
> m.add(s,p,"text","en");
>
> StmtIterator it = m.listStatements(s, p, null,"en");
> // list all the statements - not what one can expect
> for (;it.hasNext();) {
> System.out.println(it.next());
> }
> }
> }
> TEST2
> public class LstStmt2 {
> @Test
> public final void test() {
> Model m = ModelFactory.createDefaultModel();
> Resource s = m.createResource("http://www.a.com/s";);
> Property p = m.createProperty("http://www.a.com/p";);
> m.add(s,p,"text","en");
> m.add(s,p,"text");
>
> StmtIterator it = m.listStatements(s, p,"text",null);
> // should list the 2 statements, but doesn't: only the one
> without lang
> for (;it.hasNext();) {
> System.out.println(it.next());
> }
> }
