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 = 0 ); | (since C++11) |
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.

Member constants
| Member | Definition |
|---|---|
const bool intl (static) | International |
Member objects
| static std::locale::id id | id of the locale (public member object) |
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 |
sign | the first of the characters returned by moneypunct::positive_sign or moneypunct::negative_sign is required |
value | the absolute numeric monetary value is required |
Example
This example demonistrates how to apply monetary formatting rules of another language without changing the rest of the locale.
#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
