std::time_get_byname is a std::time_get facet which encapsulates time and date parsing rules of the locale specified at its construction.

Two specializations are provided by the standard library

Defined in header <locale>
std::time_get_byname<char, InputIt>	narrow/multibyte time parsing
std::time_get_byname<wchar_t, InputIt>	wide string time parsing

Member functions

(constructor)	constructs a new time_get_byname facet (public member function)
(destructor)	destroys a time_get_byname facet (protected member function)

std::time_get_byname::time_get_byname

explicit time_get_byname( const char* name, std::size_t refs = 0 );
explicit time_get_byname( const std::string& name, std::size_t refs = 0 );		(since C++11)

Constructs a new std::time_get_byname facet for a locale with name.

refs is used for resource management: if refs == 0, the implementation destroys the facet, when the last std::locale object holding it is destroyed. Otherwise, the object is not destroyed.

Parameters

name	-	the name of the locale
refs	-	the number of references that link to the facet

std::time_get_byname::~time_get_byname

protected: ~time_get_byname();

Destroys the facet.

id (static)	std::locale::id

Member functions

date_order	invokes do_date_order (public member function of std::time_get)
get_time	invokes do_get_time (public member function of std::time_get)
get_date	invokes do_get_date (public member function of std::time_get)

get_year	invokes do_get_year (public member function of std::time_get)
get (C++11)	invokes do_get (public member function of std::time_get)

Protected member functions

do_date_order [virtual]	obtains preferred ordering of day, month, and year (virtual protected member function of std::time_get)
do_get_time [virtual]	extracts hours, minutes, and seconds from input stream (virtual protected member function of std::time_get)
do_get_date [virtual]	extracts month, day, and year from input stream (virtual protected member function of std::time_get)
do_get_weekday [virtual]	extracts the name of a day of the week from input stream (virtual protected member function of std::time_get)
do_get_monthname [virtual]	extacts a month name from input stream (virtual protected member function of std::time_get)
do_get_year [virtual]	extracts a year from input stream (virtual protected member function of std::time_get)
do_get [virtual] (C++11)	extracts date/time components from input stream, according to the specified format (virtual protected member function of std::time_get)

Inherited from std::time_base

Type	Definition
dateorder	date order enumeration type, defining the values no_order, dmy, mdy, ymd, and ydm
