Class IC<J extends SimJob,Q extends IC>

java.lang.Object

org.javades.jqueues.r5.entity.AbstractSimEntity

org.javades.jqueues.r5.entity.jq.AbstractSimJQ<J,Q>

org.javades.jqueues.r5.entity.jq.queue.AbstractSimQueue<J,Q>

org.javades.jqueues.r5.entity.jq.queue.nonpreemptive.AbstractNonPreemptiveWorkConservingSimQueue<J,Q>

org.javades.jqueues.r5.entity.jq.queue.nonpreemptive.IC<J,Q>

Type Parameters:

J - The type of SimJobs supported.

Q - The type of SimQueues supported.

All Implemented Interfaces:

SimQueue<J,Q>, SimQoS<J,Q>, SimEntity, org.javades.jsimulation.r5.SimEventListResetListener

public class IC<J extends SimJob,Q extends IC>
extends AbstractNonPreemptiveWorkConservingSimQueue<J,Q>
implements SimQoS<J,Q>

The IC queue serves all jobs in zero time. Infinite Capacity.

This queueing discipline guarantees that it will never invoke SimJob.getServiceTime(Q).

In the presence of vacations, i.e., jobs are not immediately admitted to service, this implementation respects the arrival order of jobs.
