@page LEVEL3 Scheduled Job Queue Requirements.

|

The ScheduledJobQueue is a helper object to the Scheduler. This object
|
||||
keeps an ordered queue of the jobs for a particular job class. The Scheduler adds
|
||||
and removes jobs from the queue. The Scheduler asks for the top job of the
|
||||
queue, or the next job that has an execution time that matches the current simulation time.
|
||||
Finally, the Scheduler asks the ScheduledJobQueue to insert an
|
||||
instrumentation job where the job is attached before or after a specific job in the queue,
|
||||
or attached before or after all jobs in the simulation.

||||
