Method Detail

toString

public String toString()

Overrides:

toString in class SimQueuePredictor_FCFS

createQueueState

public SimQueueState<SimJob,SimQueue> createQueueState(SimQueue queue,
                                                       boolean isROEL)

Registers a new SimQueueQoSStateHandler at the object created by super method.

Parameters:

queue - The queue, non-null.

isStartArmed

public boolean isStartArmed(SimQueue queue,
                            SimQueueState<SimJob,SimQueue> queueState)

Description copied from interface: SimQueueStatePredictor

Checks whether a given state represents StartArmed on given queue.

Specified by:

isStartArmed in interface SimQueueStatePredictor<SimQueue>

Overrides:

isStartArmed in class SimQueuePredictor_FCFS

Parameters:

queue - The queue.

queueState - The queue state, non-null.

Returns:

True if the state represents StartArmed at given queue.

getJobToStart

protected SimJob getJobToStart(SimQueue queue,
                               SimQueueState<SimJob,SimQueue> queueState)
                        throws SimQueuePredictionException

Overrides:

getJobToStart in class SimQueuePredictor_FCFS

Throws:

SimQueuePredictionException

doWorkloadEvents_SQ_SV_ROEL_U

public void doWorkloadEvents_SQ_SV_ROEL_U(SimQueue queue,
                                          WorkloadSchedule_SQ_SV_ROEL_U workloadSchedule,

                                          WorkloadScheduleException

Description copied from interface: SimQueueEventPredictor

Process the next event(s) from given WorkloadSchedule at a queue with given state.

The scheduled time and the types of the next events must be known beforehand, e.g., through WorkloadSchedule.getNextEventTimeBeyond(org.javades.jqueues.r5.entity.jq.queue.SimQueue, double, java.util.Set<org.javades.jqueues.r5.entity.SimEntitySimpleEventType.Member>). The scheduled time has already been set on the SimQueueState object, and the object has been updated upto that time. The time on the queue state must not be changed.

Implementations must update the queue state and (if applicable) add suitable entries to the visit logs.

Implementations must not modify the workload schedule.

Specified by:

doWorkloadEvents_SQ_SV_ROEL_U in interface SimQueueEventPredictor<SimQueue>

Overrides:

doWorkloadEvents_SQ_SV_ROEL_U in class SimQueuePredictor_FCFS

Parameters:

queue - The queue, non-null.

workloadSchedule - The workload schedule, non-null.

queueState - The queue-state, non-null.

workloadEventTypes - The (pre-calculated) types of the next workload event(s).

visitLogsSet - The visit logs, non-null.

Throws:

SimQueuePredictionException - If the result cannot be computed, e.g., due to invalid input or schedule ambiguities.

WorkloadScheduleException - If the workload is invalid (e.g., containing ambiguities).

                                throws SimQueuePredictionException

Description copied from interface: SimQueueEventPredictor

Process the next event(s) at a queue with given state.

The scheduled time and the types of the next events must be known beforehand, e.g., through SimQueueEventPredictor.getNextQueueEventTimeBeyond(Q, org.javades.jqueues.r5.util.predictor.state.SimQueueState<org.javades.jqueues.r5.entity.jq.job.SimJob, Q>, java.util.Set<org.javades.jqueues.r5.entity.SimEntitySimpleEventType.Member>). The scheduled time has already been set on the SimQueueState object, and the object has been updated upto that time. The time on the queue state must not be changed.

Implementations must update the queue state and (if applicable) add suitable entries to the visit logs.

Specified by:

doQueueEvents_SQ_SV_ROEL_U in interface SimQueueEventPredictor<SimQueue>

Overrides:

doQueueEvents_SQ_SV_ROEL_U in class SimQueuePredictor_FCFS

Parameters:

queue - The queue, non-null.

queueState - The queue-state, non-null

queueEventTypes - The (pre-calculated) types of the next workload event(s).

visitLogsSet - The visit logs, non-null.

Throws:

SimQueuePredictionException - If the result cannot be computed, e.g., due to invalid input or schedule ambiguities.
