    • Method Detail

      • addCharacters

        void addCharacters​(char[] buf,
                           int start,
                           int len)
        Passes an additional fragment of the literal.

        The application can call this method several times, then call the isValid method (or the checkValid method) to check the validity of the accumulated characters.

      • isValid

        boolean isValid()
        Tells if the accumulated literal is valid with respect to the underlying Datatype.
        Returns:
        True if it is valid. False if otherwise.
      • checkValid

        void checkValid()
                 throws DatatypeException
        Similar to the isValid method, but this method throws Exception (with possibly diagnostic information), instead of returning false.
        Throws:
        DatatypeException - If the callee supports the diagnosis and the accumulated literal is invalid, then this exception that possibly contains diagnosis information is thrown.
