      public BNode createBNode()
      Description copied from interface: ValueFactory
      Creates a new bNode.
      Specified by:
      createBNode in interface ValueFactory
      Returns:
      An object representing the bNode.

    • createBNode

      public BNode createBNode(String nodeID)
      Description copied from interface: ValueFactory
      Creates a new blank node with the given node identifier.
      Specified by:

    • createIRI

      public IRI createIRI(String iri)
      Description copied from interface: ValueFactory
      Creates a new IRI from the supplied string-representation.
      Specified by:
      createIRI in interface ValueFactory
      Parameters:
      iri - A string-representation of a IRI.

    • createIRI

      public IRI createIRI(String namespace, String localName)
      Description copied from interface: ValueFactory
      Creates a new IRI from the supplied namespace and local name. Calling this method is funtionally equivalent to calling createIRI(namespace+localName), but allows the ValueFactory to reuse supplied namespace and local name strings whenever possible. Note that the values returned by IRI.getNamespace() and IRI.getLocalName() are not necessarily the same as the values that are supplied to this method.
      Specified by:
      createIRI in interface ValueFactory
      Parameters:
      namespace - The IRI's namespace.
      localName - The IRI's local name.
