      • getDatatypeURIs

        public static List<String> getDatatypeURIs()
        Gets a List of all datatype URIs.
        Returns:
        a List the datatype URIs

      • isFloat

        public static boolean isFloat​(String datatypeURI)
        Checks if a given URI is a numeric floating point datatype URI: xsd:decimal, xsd:float or xsd:double.
        Parameters:
        datatypeURI - the URI of the datatype to test
        Returns:
        true if so

      • isNumeric

        public static boolean isNumeric​(String datatypeURI)
        Checks if a given URI is a numeric datatype URI.
        Parameters:
        datatypeURI - the URI of the datatype to test
        Returns:
        true if so

      • isSystemDatatype

        public static boolean isSystemDatatype​(org.apache.jena.rdf.model.RDFNode node)
        Checks if a given RDFNode represents a system XSD datatype such as xsd:int. Note: this will not return true on user-defined datatypes or rdfs:Literal.
        Parameters:
        node - the node to test
        Returns:
        true if node is a datatype
