class wbuffer_convert : public std::basic_streambuf<Elem, Tr>
(depuis C++11)
std::wbuffer_convert est un wrapper sur tampon de flux de std::basic_streambuf<char> type qui lui donne l'apparence d'std::basic_streambuf<Elem>. Toutes les E / S exécutées par std::wbuffer_convert subit une conversion de caractères telle que définie par la Codecvt facette. std::wbuffer_convert assume la propriété de la facette de conversion, et ne peut pas utiliser une facette géré par une locale. Les facettes standards appropriés pour une utilisation avec std::wbuffer_convert sont std::codecvt_utf8 pour UTF-8/UCS2 et UTF-8/UCS4 conversions et std::codecvt_utf8_utf16 pour UTF-8/UTF-16 conversions .
Original:
std::wbuffer_convert is a wrapper over stream buffer of type std::basic_streambuf<char> which gives it the appearance of std::basic_streambuf<Elem>. All I/O performed through std::wbuffer_convert undergoes character conversion as defined by the facet Codecvt. std::wbuffer_convert assumes ownership of the conversion facet, and cannot use a facet managed by a locale. The standard facets suitable for use with std::wbuffer_convert are std::codecvt_utf8 for UTF-8/UCS2 and UTF-8/UCS4 conversions and std::codecvt_utf8_utf16 for UTF-8/UTF-16 conversions.
