All Implemented Interfaces:

Controllable

public class AlarmClock
extends Object
implements Controllable

The alarm clock sends events at specified times in the future. A caller may use the AlarmClock.add(long, com.connecterra.util.event.EventReceiver, java.lang.Object) method of the alarm clock to schedule the delivery of a specified event to a specified event receiver, at a specified time (measured as an offset from the current time). Or, a caller may use the AbstractEventProcessor.doLater(long, com.connecterra.util.event.Event) method. The alarm clock operates an independent thread that delivers such events when their time comes.
