NAMEmoney_put
- Monetary formatting facet for output.
SYNOPSIS
#include <locale>
template <class charT,
class OutputIterator = ostreambuf_iterator<charT> >
class money_put;
DESCRIPTION
The money_put_facet takes a long double value, or generic sequence of
digits and writes out a formatted representation of the monetary value.
INTERFACE
template <class charT,
class OutputIterator = ostreambuf_iterator<charT> >
class money_put : public locale::facet {
public:
typedef charT char_type;
typedef OutputIterator iter_type;
typedef basic_string<charT> string_type;
explicit money_put(size_t = 0);
iter_type put(iter_type, bool, ios_base&, char_type,
long double) const;
iter_type put(iter_type, bool, ios_base&, char_type,
const string_type&) const;
static locale::id id;
protected:
~money_put(); // virtual
virtual iter_type do_put(iter_type, bool, ios_base&,
char_type, long double) const;
virtual iter_type do_put(iter_type, bool, ios_base&,
char_type, const string_type&)
const;
};
TYPES
char_type
Type of the character upon which the facet is instantiated.
iter_type
Type of iterator used to scan the character buffer.
string_type
Type of character string passed to member functions.
CONSTRUCTORS
explicit money_put(size_t refs = 0)
Construct a money_put facet. If the refs argument is 0, then destruction of
the object is delegated to the locale, or locales, containing it. This
allows the user to ignore lifetime management issues. On the other hand, if
refs is 1, then the object must be explicitly deleted; the locale does not
do so.
DESTRUCTORS
~money_put(); // virtual and protected
Destroys the facet.
STATIC MEMBERS
static locale::id id;
Unique identifier for this type of facet.
PUBLIC MEMBER FUNCTIONS
The public members of the money_put facet include an interface to pro‐
tected members. Each public member put has a corresponding virtual pro‐
tected member do_put.
iter_type
put(iter_type s, bool intl, ios_base& f, char_type fill,
long double units) const;
iter_typeput(iter_type s, bool intl, ios_base& f, char_type fill,
const string_type& digits) const;
Each of these two overloads of the public member function put simply calls
the corresponding protected do_put function.
PROTECTED MEMBER FUNCTIONSvirtual iter_typedo_put(iter_type s, bool intl, ios_base& f, char_type fill,
long double units) const;
Writes out a character string representation of the monetary value con‐
tained in units. Since units represents the monetary value in the smallest
possible unit of currency, any fractional portions of the value are
ignored. f.flags() and the moneypunct<charT, intl> facet from f.getloc()
give the formatting information.
The fill argument is used for any padding.
Returns an iterator pointing one past the last character written.
virtual iter_typedo_put(iter_type s, bool intl, ios_base& f, char_type fill,
const string_type& digits) const;
Writes out a character string representation of the monetary value con‐
tained in digits. digits represents the monetary value as a sequence of
digits in the smallest possible unit of currency. do_put only looks at an
optional - character and any immediately contiguous digits. f.flags() and
the moneypunct<charT, intl> facet from f.getloc() give the formatting
information.
The fill argument is used for any padding.
Returns an iterator pointing one past the last character written.
EXAMPLE
//
// moneyput.cpp
//
#include <string>
#include <iostream>
int main ()
{
using namespace std;
typedef ostreambuf_iterator<char,char_traits<char> >
iter_type;
locale loc;
string buffer("10002");
long double ldval = 10002;
// Construct a ostreambuf_iterator on cout
iter_type begin(cout);
// Get a money put facet
const money_put<char,iter_type>& mp =
#ifndef _RWSTD_NO_TEMPLATE_ON_RETURN_TYPE
use_facet<money_put<char,iter_type> >(loc);
#else
use_facet(loc,(money_put<char,iter_type>*)0);
#endif
// Put out the string representation of the monetary value
cout << buffer << " --> ";
mp.put(begin,false,cout,' ',buffer);
// Put out the long double representation
// of the monetary value
cout << endl << ldval << " --> ";
mp.put(begin,false,cout,' ',ldval);
cout << endl;
return 0;
