std::time_put_byname – std::time_put_byname

Synopsis

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

Member functions

              constructs a new time_put_byname facet
constructor (public member function)
              destroys a time_put_byname facet
destructor (protected member function)

 std::time_put_byname::time_put_byname

explicit time_put_byname( const char* name, std::size_t refs = 0 );
explicit time_put_byname( const std::string& name, std::size_t refs = 0 ); (since C++11)

Constructs a new std::time_put_byname facet for a locale with name.
refs is used for resource management: if refs == 0, the implementation destroys the facet, when the last std::locale object holding it is destroyed. Otherwise, the object is not destroyed.

Parameters

name – the name of the locale
refs – the number of references that link to the facet

 std::time_put_byname::~time_put_byname

protected:
~time_put_byname();

Destroys the facet.

Inherited from std::time_put

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';
}
