Detailed Description
template<typename _CharT, typename _InIter> class std::money_get< _CharT,
_InIter >
Facet for parsing monetary amounts.
This facet encapsulates the code to parse and return a monetary amount
from a string.
The money_get template uses protected virtual functions to provide the
actual results. The public accessors forward the call to the virtual
functions. These virtual functions are hooks for developers to
implement the behavior they require from the money_get facet.

Constructor & Destructor Documentation
template<typename _CharT , typename _InIter > std::money_get< _CharT,
_InIter >::money_get (size_t __refs = 0) [inline, explicit]
Constructor performs initialization. This is the constructor provided
by the standard.
Parameters:
refs Passed to the base facet class.

const [inline, protected, virtual]
Read and parse a monetary value. This function reads and parses
characters representing a monetary value. This function is a hook for
derived classes to change the value returned.

_CharT, _InIter >::get (iter_type __s, iter_type __end, bool __intl,
ios_base & __io, ios_base::iostate & __err, string_type & __digits)
const [inline]
Read and parse a monetary value. This function reads characters from s,
interprets them as a monetary value according to moneypunct and ctype
facets retrieved from io.getloc(), and returns the result in digits.
For example, the string $10.01 in a US locale would store '1001' in
digits.
Any characters not part of a valid money amount are not consumed.
If a money value cannot be parsed from the input stream, sets
err=(err|io.failbit). If the stream is consumed before finishing
parsing, sets err=(err|io.failbit|io.eofbit).
This function works by returning the result of do_get().
Parameters:
s Start of characters to parse.
end End of characters to parse.
intl Parameter to use_facet<moneypunct<CharT,intl> >.
io Source of facets and io state.
err Error field to set if parsing fails.
digits Place to store result of parsing.
Returns:
Iterator referencing first character beyond valid money amount.

ios_base & __io, ios_base::iostate & __err, long double & __units)
const [inline]
Read and parse a monetary value. This function reads characters from s,
interprets them as a monetary value according to moneypunct and ctype
facets retrieved from io.getloc(), and returns the result in units as
an integral value moneypunct::frac_digits() * the actual amount. For
example, the string $10.01 in a US locale would store 1001 in units.
Any characters not part of a valid money amount are not consumed.
If a money value cannot be parsed from the input stream, sets
err=(err|io.failbit). If the stream is consumed before finishing
parsing, sets err=(err|io.failbit|io.eofbit). units is unchanged if
parsing fails.
This function works by returning the result of do_get().
Parameters:
s Start of characters to parse.
end End of characters to parse.
intl Parameter to use_facet<moneypunct<CharT,intl> >.
io Source of facets and io state.
err Error field to set if parsing fails.
units Place to store result of parsing.
Returns:
Iterator referencing first character beyond valid money amount.
