      Create a LangTag object, using the Jena system default implementation of the LangTag interface. The string must conform to the syntax defined in rules and syntax in RFC 5646

    • formatLanguageTag

      public static String formatLanguageTag(String langTagStr)
      Prepare the language tag - apply formatting normalization, and always return a string. If the input is invalid as a language tag, return the input as-is.

      JenaException - on an all blank string.

    • checkLanguageTag

      public static boolean checkLanguageTag(String langTagStr)
      Check a string is valid as a language tag. This function returns true or false and does not throw an exception.

    • checkLanguageTagBasicSyntax

      public static boolean checkLanguageTagBasicSyntax(String langTagStr)
      Check a language tag string meets the Turtle(etc) and SPARQL grammar rule for a language tag without initial text direction.

      Passing this test does not guarantee the string is valid language tag. Use checkLanguageTag(String) for validity checking.

    • requireValidLanguageTag

      public static void requireValidLanguageTag(String langTagStr)
      Check a string is valid as a language tag. Throw a JenaException if it is not valid.
