std::time_get(3)
NAME
std::time_get
SYNOPSIS
Inherits std::locale::facet, and std::time_base. Inherited by std::time_get_byname< _CharT, _InIter >.
Detailed Description
- template<typename _CharT, typename _InIter> class std::time_get< _CharT,
- _InIter >
Facet for parsing dates and times. - This facet encapsulates the code to parse and return a date or time
from a string. It is used by the istream numeric extraction operators. - The time_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 time_get facet. - Definition at line 366 of file locale_facets_nonio.h.

Member Function Documentation
- template<typename _CharT, typename _InIter> dateorder std::time_get<
- _CharT, _InIter >::date_order () const [inline] Return preferred order of month, day, and year.
- This function returns an enum from timebase::dateorder giving the
preferred ordering if the format 'x' given to time_put::put() only uses month, day, and year. If the format 'x' for the associated locale uses other fields, this function returns timebase::dateorder::noorder. - NOTE: The library always returns noorder at the moment.
- Returns:
A member of timebase::dateorder.

- _CharT, _InIter >::get_date (iter_type __beg, iter_type __end, ios_base & __io, ios_base::iostate & __err, tm * __tm) const [inline] Parse input date string.
- This function parses a date according to the format 'X' and puts the
results into a user-supplied struct tm. The result is returned by
calling time_get::do_get_date(). - If there is a valid date string according to format 'X', tm will be
filled in accordingly and the returned iterator will point to the first
character beyond the date string. If an error occurs before the end,
err |= ios_base::failbit. If parsing reads all the characters, err |= ios_base::eofbit. - Parameters:
beg Start of string to parse.
end End of string to parse.

- _CharT, _InIter >::get_monthname (iter_type __beg, iter_type __end, ios_base & __io, ios_base::iostate & __err, tm * __tm) const [inline] Parse input month string.
- This function parses a month name and puts the results into a usersupplied struct tm. The result is returned by calling
time_get::do_get_monthname(). - Parsing starts by parsing an abbreviated month name. If a valid
abbreviation is followed by a character that would lead to the full
month name, parsing continues until the full name is found or an error occurs. Otherwise parsing finishes at the end of the abbreviated name. - If an error occurs before the end, err |= ios_base::failbit. If parsing reads all the characters, err |= ios_base::eofbit.
- Parameters:
beg Start of string to parse.
end End of string to parse.

- _CharT, _InIter >::get_year (iter_type __beg, iter_type __end, ios_base & __io, ios_base::iostate & __err, tm * __tm) const [inline] Parse input year string.
- This function reads up to 4 characters to parse a year string and puts
the results into a user-supplied struct tm. The result is returned by
calling time_get::do_get_year(). - 4 consecutive digits are interpreted as a full year. If there are
exactly 2 consecutive digits, the library interprets this as the number of years since 1900. - If an error occurs before the end, err |= ios_base::failbit. If parsing reads all the characters, err |= ios_base::eofbit.
- Parameters:
beg Start of string to parse.
end End of string to parse.
