      extends Object

  Factory methods to quickly create `Value` objects ( `IRI`, `Literal`, `BNode`, and `Triple`) without having to create a `ValueFactory` first.

  Example usage:

       import static org.eclipse.rdf4j.model.util.Values.iri;

       ...
       IRI foo = iri("http://example.org/foo");
