Detailed Description
template<typename _CharT, typename _InIter>
class std::money_get< _CharT, _InIter >" Primary class template
money_get.
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.
template<typename _CharT , typename _InIter > virtual std::money_get<
_CharT, _InIter >::~money_get () [inline], [protected], [virtual]
Destructor.

const [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, 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.

const [inline]
Read and parse a monetary value. This function reads characters from
__s, interprets them as a monetary value according to moneypunct and

Parameters
__s Start of characters to parse.
__end End of characters to parse.
__intl Parameter to use_facet<moneypunct<CharT,intl> >.

__err Error field to set if parsing fails.
__digits Place to store result of parsing.
Returns
Iterator referencing first character beyond valid money amount.
