C++
 
Localization library
 
Defined in header <locale>
template< class CharT, class OutputIterator = std::ostreambuf_iterator<CharT> >
class time_put_byname : public std::time_put<CharT, OutputIterator>;

std::time_put_byname is a std::time_put facet which encapsulates time and date formatting rules of the locale specified at its construction.

Two specializations are provided by the standard library

Defined in header <locale>
std::time_put_byname<char, OutputIterator> narrow/multibyte time formatting
std::time_put_byname<wchar_t, OutputIterator> wide string time formatting

Contents

Member types

Member type Definition
char_type CharT
iter_type OutputIterator

Member functions

 constructs a new time_put_byname facet
(public member function)
destructs a time_put_byname facet
(protected member function)

Inherited from std::time_put

Member objects

Member name Type
id (static) std::locale::id

Member functions

 invokes do_put
(public member function of std::time_put<CharT,OutputIt>) [edit]

Protected member functions

[virtual]
 formats date/time and writes to output stream
(virtual protected member function of std::time_put<CharT,OutputIt>) [edit]

Example

This example prints current time using the "C" locale with the time_put facet replaced by various time_put_byname facets

Run this code
#include <iostream>
#include <ctime>
#include <iomanip>
#include <codecvt>
 
int main()
{
    std::time_t t = std::time(NULL);
    std::wbuffer_convert<std::codecvt_utf8<wchar_t>> conv(std::cout.rdbuf());
    std::wostream out(&conv);
 
    out.imbue(std::locale(out.getloc(),
                          new std::time_put_byname<wchar_t>("ja_JP")));
    out << std::put_time(std::localtime(&t), L"%A %c") << '\n';
 
    out.imbue(std::locale(out.getloc(),
                         new std::time_put_byname<wchar_t>("ru_RU.utf8")));
    out << std::put_time(std::localtime(&t), L"%A %c") << '\n'; 
 
    out.imbue(std::locale(out.getloc(),
                         new std::time_put_byname<wchar_t>("sv_SE.utf8")));
    out << std::put_time(std::localtime(&t), L"%A %c") << '\n'; 
}
