timer

问题 How can I access all the member field of the class which contains the function initTimer() from within the AbstractActionClass? Thanks private void initTimer() { Action updateClockAction = new AbstractAction() { public void actionPerformed(ActionEvent e){ JLabel secLabel = m_GameApplet.GetJpanelStartNetGame().GetJlabelSeconds(); secLabel.setFont(new java.awt.Font("Lucida Handwriting", 1, 36)); secLabel.setForeground(Color.red); secLabel.setText(Integer.toString(m_TimerSeconds)); if(m

问题 In a previous post, I used the observer pattern. Description - class Flight has a status (ie int) - before time, on time, late. This is my Observable class FlightStatusMonitor has an ArrayList of Flights. This class is my observer. There is only one such observer. The update(Observable o, Object arg) method will update the status of the flight and also display the refreshed flight status of all flights that it observes. I was thinking of using timer tasks to change the status of flights at

问题 I have an .ear file which is composed of multiple EJB's and one of them do use a timer service to create timer and the same ejb has the callback method too. That ear is supposed to be deployed in a clustered environment of 3 servers. The issue now is that i want to know what is the expected behavior if i redeployed/undeployed the ear in the cluster. Will the server cancel all timers and clear the persistent scheduler? Or it will preserve them? What are the work arounds? I have read that in

问题 I have the following timer: setCountDown() { let counter = 5; let tick = 1000; this.countDown = timer(0, tick) .pipe( take(counter), map(() => --counter), finalize(() => { if (this.currentQuestionNumber < this.questionsToAsk) this.showNextQuestion(); else { this.endQuiz(); } }) ); } How can I stop the timer? E.g. when a user clicks on a button... 回答1: assuming you are using angular, if you use javascript only you can just us fromEvent() to create userClick userClick=new Subject() click()

问题 I stack a bit so if anyone has any ideas it would be helpful. So currently the program is compiling and running but I do not know how to finish it. I am using eclipse. What i want to do is when i start the program to change 4 different pictures in every 2 seconds so if you have any advices do not be shy. Here is the program. /** Here is the GUI of the program * class name SlideShowGui.java * @author Kiril Anastasov * @date 07/03/2012 */ import java.awt.*; import java.awt.event.ActionEvent;

问题 I want to fire a recursive function every 10 milliseconds, but setTimeout doesn't seem to take any value under 100, no matter what I put. decrementCountdown = function() { console.log('fired'); t = setTimeout("decrementCountdown()", 100); } Why can't I set a value under 1000 milliseconds? EDIT : Looks like my timer is firing correctly...the problem is when I use it to call a function ( like Jquery's html() ). Even though setTimeout is calling the function at correct intervals, it won't fire

问题 The app is in the background and it receives a callback upon disconnection with the BLE device, after which the app has to wait for sometime(1minute) and then execute some piece of code. The app behaves as expected even when in the background if the screen is turned on. But if the screen is turned off then the timer is not working and the app is not executing as expected. This is the code in AppDelegate to start a timer in background: func startTimerWith(timeInterval: TimeInterval) {
