      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:
        `createBNode` in interface `ValueFactory`
      Parameters:
        `nodeID` - The blank node identifier.
      Returns:
        An object representing the blank node.

    - #### 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.
