calendar.h ~ calendar ~ year_type

namespace calendar::year { typedef /* implementation defined */ year_type; }

Description

Defines integer type to store the representation of Gregorian years.

An ISO 8601 valid year_type must have a value between 1 and 292277025, in which case it can be safely handled as a year parameter such as in datetime_type or class Date constructor, otherwise the program is ill-formed.

Examples

In the following example, we create a valid date with the year specified by user input.

#include <iostream>
#include <JLC/JLC.h>
using namespace JLC;
using namespace calendar::year;

int main(){
    year_type year;
    do{
        std::cout << "year = ";
        std::cin >> year;
    }while(!debug::verify(std::cin));
    std::cout << Date(year) << std::endl;
}

year = test
year = 0
year = 2012
2012-01-01T00:00:00+0000
