public class SimpleEventScheduler extends Object implements EventScheduler
EventScheduler
implementation that uses Java's ScheduledExecutorService as scheduling and triggering
mechanism.
Note that this mechanism is non-persistent. Scheduled tasks will be lost when the JVM is shut down, unless special
measures have been taken to prevent that. For more flexible and powerful scheduling options, see QuartzEventScheduler
