Constructor Detail

AbstractServerlessSimQueue

public AbstractServerlessSimQueue(org.javades.jsimulation.r5.SimEventList eventList,
                                  int bufferSize)

Creates a server-less queue given an event list and buffer size.

Parameters:

eventList - The event list to use.

bufferSize - The buffer size (non-negative), Integer.MAX_VALUE is interpreted as infinity.

Method Detail

queueAccessVacationDropSubClass

protected final void queueAccessVacationDropSubClass(double time,
                                                     J job)

Calls super method (in order to make implementation final).

Overrides:

queueAccessVacationDropSubClass in class AbstractSimQueue<J extends SimJob,Q extends AbstractServerlessSimQueue>

Parameters:

time - The time the job was dropped, i.e., the current time.

job - The dropped job.

See Also:

AbstractSimQueue.arrive(double, J), AbstractSimQueue.setQueueAccessVacation(double, boolean)

isStartArmed

public final boolean isStartArmed()

Returns false since jobs cannot start.

Returns:

false.

See Also:

SimQueueListener.notifyNewStartArmed(double, Q, boolean)

insertJobInQueueUponStart

protected final void insertJobInQueueUponStart(J job,
                                               double time)

Throws IllegalStateException.

Specified by:

insertJobInQueueUponStart in class AbstractSimQueue<J extends SimJob,Q extends AbstractServerlessSimQueue>

Parameters:

job - The job that starts.

time - The current time (i.e., start time of the job).

Throws:

IllegalStateException - Always, as a call to this method is unexpected.

See Also:

AbstractSimQueue.start(double, J), AbstractSimQueue.rescheduleAfterStart(J, double)

rescheduleAfterStart

protected final void rescheduleAfterStart(J job,
                                          double time)

Throws IllegalStateException.

Specified by:

rescheduleAfterStart in class AbstractSimQueue<J extends SimJob,Q extends AbstractServerlessSimQueue>

Parameters:

job - The job that started (and is already present in AbstractSimQueue.getJobsInServiceArea().

time - The current time (i.e., the start time of the job).

Throws:

IllegalStateException - Always, as a call to this method is unexpected.

See Also:

AbstractSimQueue.start(double, J), AbstractSimQueue.insertJobInQueueUponStart(J, double)

setServerAccessCreditsSubClass

protected final void setServerAccessCreditsSubClass()

Calls super method and makes method final; does nothing since we are server-less.

Overrides:

setServerAccessCreditsSubClass in class AbstractSimQueue<J extends SimJob,Q extends AbstractServerlessSimQueue>

See Also:

AbstractSimQueue.getServerAccessCredits(), AbstractSimQueue.setServerAccessCredits(double, int), AbstractSimQueue.rescheduleForNewServerAccessCredits(double)

rescheduleForNewServerAccessCredits

protected final void rescheduleForNewServerAccessCredits(double time)

Does nothing, since we are server-less.

Specified by:

rescheduleForNewServerAccessCredits in class AbstractSimQueue<J extends SimJob,Q extends AbstractServerlessSimQueue>

Parameters:

time - The current time (i.e., the time at which new server-access credits became available).

See Also:

AbstractSimQueue.setServerAccessCredits(double, int), AbstractSimQueue.hasServerAcccessCredits()

getServiceTimeForJob

protected final double getServiceTimeForJob(J job)

Throws IllegalStateException.

Overrides:

getServiceTimeForJob in class AbstractSimQueue<J extends SimJob,Q extends AbstractServerlessSimQueue>

Parameters:

job - The job, non-null.

Returns:

The required service time, non-negative.

Throws:

IllegalStateException - Always, as a call to this method is unexpected.
