public interface Scheduler

extends SchedulerServiceMBean

a scheduler provides the basic ability to run a given task at a given time. That's it. Of course, all kinds of fancy functionality can be built on top of this -- cron, one-shot events, periodic background tasks, etc.

There are no restrictions on what a Runnable do. For example, they can change their thread priorities and therefore run at a lower or higher priority than other tasks even if they are scheduled for the same exact time.

A scheduler parallels a thread in many ways. A Runnable encapsulates a basic unit of work for either a Thread or a Scheduler. A runnable can certianly reschedule itself, return immediately, or whatever.
