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.

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.
