NAME

std::moneypunct_byname - std::moneypunct_byname

Synopsis

Defined in header <locale>
template< class CharT, bool Intl = false >
class moneypunct_byname : public std::moneypunct<CharT, Intl>;

std::moneypunct_byname is a std::moneypunct facet which encapsulates monetary
formatting preferences of a locale specified at its construction.

Two specializations are provided by the standard library

Defined in header <locale>
std::moneypunct_byname<char, Intl> locale-specific std::moneypunct facet for
narrow character I/O
std::moneypunct_byname<wchar_t, Intl> locale-specific std::moneypunct facet for wide
character I/O

Member functions

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

std::moneypunct_byname::moneypunct_byname

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

Constructs a new std::moneypunct_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::moneypunct_byname::~moneypunct_byname

protected:
~moneypunct_byname();

Destroys the facet.

Inherited from std::money_base

Member type Definition
enum part { none, space, symbol, sign, value }; unscoped enumeration type
struct pattern { char field[4]; }; the monetary format type

Enumeration constant Definition
none whitespace is permitted but not required except in the last
position, where whitespace is not permitted
space one or more whitespace characters are required
symbol the sequence of characters returned by moneypunct::curr_symbol
is required
the first of the characters returned by
sign moneypunct::positive_sign or moneypunct::negative_sign is
required
value the absolute numeric monetary value is required

Example

This example demonstrates how to apply monetary formatting rules of another language
without changing the rest of the locale.

// Run this code

#include <iostream>
#include <iomanip>
#include <locale>
int main()
{
long double mon = 1234567;
std::locale::global(std::locale("en_US.utf8"));
std::wcout.imbue(std::locale());
std::wcout << L"american locale : " << std::showbase
<< std::put_money(mon) << '\n';
std::wcout.imbue(std::locale(std::wcout.getloc(),
new std::moneypunct_byname<wchar_t>("ru_RU.utf8")));
std::wcout << L"american locale with russian moneypunct: "
<< std::put_money(mon) << '\n';
}

Output:

american locale : $12,345.67
american locale with russian moneypunct: 12 345.67 руб
