  45 /** Translate cell function keywords.
  46
  47     This class provides a convenient way to translate a string keyword used as
  48     a cell function argument.  Since Calc's built-in cell functions don't
  49     localize string keywords, this class is used mainly to deal with an Excel
  50     document where string names may be localized.
  51
  52     To use, simply call the
  53
  54        ScCellKeywordTranslator::transKeyword(...)
  55
  56     function.
  57
  58     Note that when the locale and/or the opcode is specified, the function
  59     tries to find a string with matching locale and/or opcode. But when it
  60     fails to find one that satisfies the specified locale and/or opcode, it
  61     returns a translated string with non-matching locale and/or opcode if
  62     available. */
