boost::gregorian::greg_year — Represent a year (range 1400 - 9999)
// In header: <boost/date_time/gregorian/greg_year.hpp> class greg_year : public greg_year_rep { public: // construct/copy/destruct greg_year(value_type); // public member functions BOOST_CXX14_CONSTEXPR operator value_type() const; };
This small class allows for simple conversion an integer value into a year for the gregorian calendar. This currently only allows a range of 1400 to 9999. Both ends of the range are a bit arbitrary at the moment, but they are the limits of current testing of the library. As such they may be increased in the future.
