        public static Implementation factory
        A factory for generating Restriction facets from nodes in enhanced graphs. Note: should not be invoked directly by user code: use as() instead.

      • getOnProperty

        public OntProperty getOnProperty()

        Answer the property that this property restriction applies to. If there is more than one such resource, an arbitrary selection is made (though well-defined property restrictions should not have more than one onProperty statement.
