我有以下 Java 类,我想(在概念上)移植到 python。
这个想法是你有一个闹钟线程,它会休眠 x 秒(直到第二天早上),除非设置了新的唤醒时间,此时休眠线程被中断,新的剩余时间被设置并且它在那个时间休眠。如果完成休眠,则触发闹钟声音并等待设置新的唤醒时间
我想将它移植到 Python,但我只花了几个小时在谷歌上搜索,虽然有 1001 种方法可以在 Python 中管理线程和休眠,但我找不到如何让 sleep() 持续 x 秒但也发送中断的方法。
需要明确的是,我不需要有人为我编写整个类,只需一个简单的睡眠和中断示例就足够了,这样我就可以理解它在 Python 中的完成方式。
package com.njitram.bedroomtunes.server.alarm;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import com.njitram.bedroomtunes.log.Logger;
public class AlarmThread extends Thread {
private Calendar wakeupTime;
private Alarm alarm;
/*
* Constructor to disable the alarm
*/
public AlarmThread(Alarm alarm) {
this(null, alarm);
}
public AlarmThread(Calendar wakeupTime, Alarm alarm) {
this.alarm = alarm;
if(wakeupTime == null) {
disable();
} else {
setNewWakeUpTime(wakeupTime);
}
this.start();
}
public void setNewWakeUpTime(Calendar wakeupTime) {
Logger.log("New Wake time set for AlarmThread: " + new SimpleDateFormat("dd-MM-yyyy HH:mm:ss").format(wakeupTime.getTime()));
this.wakeupTime = wakeupTime;
// If the thread was already started, it will be sleeping. Wake it up and recalculate how long it needs to sleep. Interrupting will achieve this.
this.interrupt();
}
public void disable() {
setNewWakeUpTime(getDisabledTime());
}
private Calendar getDisabledTime() {
// The idea is to disable the alarm. If the alarm eventually goes off in the year 3000, I deserve to wake up...
Calendar wakeupTime = Calendar.getInstance();
wakeupTime.set(Calendar.YEAR, 3000);
return wakeupTime;
}
千万里不及你
