      Déclaré dans l'en-tête <regex>
      template<class CharT >
      class regex_traits;
      		 (depuis C++11)
      Le modèle type de trait regex_traits fournitures std::basic_regex avec l'ensemble des types et des fonctions nécessaires pour opérer sur le CharT type .
      Original:
      The type trait template regex_traits supplies std::basic_regex with the set of types and functions necessary to operate on the type CharT.

      Comme un grand nombre d'opérations de regex sont sensibles aux paramètres régionaux (lorsque l'indicateur est réglé std::regex_constants::collate), la classe regex_traits détient généralement une instance d'une std::locale en tant que membre privé .
      Original:
      Since many of regex operations are locale-sensitive (when std::regex_constants::collate flag is set), the regex_traits class typically holds an instance of a std::locale as a private member.

      Original:
      These specializations make it possible to use std::basic_regex<char> (aka std::regex) and std::basic_regex<wchar_t> (aka std::wregex), but in order to use, for example, std::basic_regex<char32_t>, user-provided specializtion std::regex_traits<char32_t> needs to be defined.
