Detailed Description

template<typename _CharT, typename _InIter>
class std::money_get< _CharT, _InIter >

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.

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.

iter_type 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.

iter_type 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.
