  • Method Details

    • labelToASCII

      public StringBuilder labelToASCII(CharSequence label, StringBuilder dest, IDNA.Info info)
      Description copied from class: IDNA
      Converts a single domain name label into its ASCII form for DNS lookup. If any processing step fails, then info.hasErrors() will be true and the result might not be an ASCII string. The label might be modified according to the types of errors. Labels with severe errors will be left in (or turned into) their Unicode form.
      Specified by:
      labelToASCII in class IDNA
      Parameters:
      label - Input domain name label
      dest - Destination string object
      info - Output container of IDNA processing details.
      Returns:
      dest

    • labelToUnicode

      public StringBuilder labelToUnicode(CharSequence label, StringBuilder dest, IDNA.Info info)
      Description copied from class: IDNA
      Converts a single domain name label into its Unicode form for human-readable display. If any processing step fails, then info.hasErrors() will be true. The label might be modified according to the types of errors.
      Specified by:
      labelToUnicode in class IDNA
      Parameters:
      label - Input domain name label
      dest - Destination string object
      info - Output container of IDNA processing details.
      Returns:
      dest

    • nameToASCII

      public StringBuilder nameToASCII(CharSequence name, StringBuilder dest, IDNA.Info info)
      Description copied from class: IDNA
      Converts a whole domain name into its ASCII form for DNS lookup. If any processing step fails, then info.hasErrors() will be true and the result might not be an ASCII string. The domain name might be modified according to the types of errors. Labels with severe errors will be left in (or turned into) their Unicode form.
      Specified by:
      nameToASCII in class IDNA
      Parameters:
      name - Input domain name
      dest - Destination string object
      info - Output container of IDNA processing details.
      Returns:
      dest

    • nameToUnicode

      public StringBuilder nameToUnicode(CharSequence name, StringBuilder dest, IDNA.Info info)
      Description copied from class: IDNA
      Converts a whole domain name into its Unicode form for human-readable display. If any processing step fails, then info.hasErrors() will be true. The domain name might be modified according to the types of errors.
      Specified by:
      nameToUnicode in class IDNA
      Parameters:
      name - Input domain name
      dest - Destination string object
      info - Output container of IDNA processing details.
      Returns:
      dest
