class wbuffer_convert : public std::basic_streambuf<Elem, Tr>
(dal C++11)
std::wbuffer_convert è un wrapper su buffer del flusso di std::basic_streambuf<char> tipo che gli conferisce l'aspetto di std::basic_streambuf<Elem>. Tutti I / O eseguita attraverso std::wbuffer_convert subisce una conversione dei caratteri definiti dal Codecvt facet. std::wbuffer_convert si assume la proprietà della faccetta di conversione, e non può usare un aspetto gestito da un locale. Le sfaccettature tipo utilizzabili con std::wbuffer_convert sono std::codecvt_utf8 per UTF-8/UCS2 e UTF-8/UCS4 conversioni e std::codecvt_utf8_utf16 per UTF-8/UTF-16 conversioni.
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.
