Introduction to Ceylon Time platform module framework
Ceylon Time is a platform module framework in the Java class library that provides a set of tools and classes for time -related tasks.The framework aims to simplify time processing operations and provide easy -to -use APIs to handle various time -related tasks.Regardless of the differences between the calculation date, or creating and operating timetable, Ceylon Time provides a series of powerful classes and methods to meet the needs.
The following is some commonly used modules and classes in Ceylon Time:
1. Date/Time API: Ceylon Time provides a complete date and time API, including date, time, duration, and time interval.These APIs can be used for operations, comparison, and formatting of date and time.
Date date = Date(2022, 1, 1);
Time time = Time(12, 0, 0);
DateTime dateTime = date.at(time);
Duration duration = Duration.hours(2);
dateTime = dateTime.plus(duration);
Interval interval = Interval.between(dateTime, DateTime.now());
2. Timer: Ceylon Time provides a timer framework to perform tasks at the scheduled time or according to the specified interval.You can create a timer and specify the execution time and frequency of the task.
import ceylon.time.scheduler {
fixedDelay, fixedRate, once, scheduler
}
scheduler.schedule(() => {
print("Hello, Ceylon Time!");
}, once(DateTime(2022, 1, 1, 0, 0, 0)));
scheduler.schedule(() => {
print("Task executed!");
}, fixedDelay(Duration.minutes(5)));
3. timetable: Ceylon Time also provides a schedule class to create and manage time -based planning tasks.The timetable can specify the duplicate mode of the task, and allows the start and end time of the setting task.
import ceylon.time.schedule {
Schedule, CronSchedule
}
Schedule everyday = CronSchedule("0 0 8 * * ?");
Schedule weekly = CronSchedule("0 0 10 * * MON");
Schedule monthly = CronSchedule("0 0 12 1 * ?");
// Executing task at 8:00 AM every day
everyday.execute(() => {
print("Daily task executed!");
});
// Executing task at 10:00 AM every Monday
weekly.execute(() => {
print("Weekly task executed!");
});
// Executing task at 12:00 PM on the 1st day of every month
monthly.execute(() => {
print("Monthly task executed!");
});
The above is only some brief introduction to the Ceylon Time platform module framework.CEYLON TIME also provides other powerful classes and methods for handling various operations of the date and time.Its design aims to improve the efficiency of developers and provide consistent and easy -to -use APIs.Both Java developers and Ceylon developers can easily handle tasks related to time through Ceylon Time.
