    Die Art Merkmal Vorlage regex_traits liefert std::basic_regex mit dem Satz von Typen und Funktionen notwendig, von der Art CharT betreiben .
    Original:

    Da viele der regex Operationen locale-empfindlich sind (wenn std::regex_constants::collate Flag gesetzt ist), die regex_traits Klasse hält in der Regel eine Instanz einer std::locale als private Mitglied .
    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.

    std::regex_traits<char>
    std::regex_traits<wchar_t>
    Diese Spezialisierungen machen es möglich, std::basic_regex<char> (aka std::regex) und std::basic_regex<wchar_t> (aka std::wregex), aber um zu bedienen, beispielsweise std::basic_regex<char32_t> muss vom Benutzer bereitgestellten specializtion std::regex_traits<char32_t> definiert werden .
    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.
