      javax.realtime.RealtimeThread
          javax.realtime.test.preemption.Job

All Implemented Interfaces:

java.lang.Runnable, Schedulable

public class Job

extends RealtimeThread

Models jobs contending for a CPU accessed as a Resource. The actual CPU instance will be of concrete type PriorityInheritanceResource, PreemptableResource, or PriorityCeilingResource.
