hasServerAccessCredits

public boolean hasServerAccessCredits(EncTL queue,
                                      SimQueueState<SimJob,EncTL> queueState)

Description copied from interface: SimQueueStatePredictor

Checks whether a given state represents a queue-state with server-access credits available.

The default implementation returns queueState.getServerAccessCredits () > 0.

Specified by:

hasServerAccessCredits in interface SimQueueStatePredictor<EncTL>

Parameters:

queue - The queue.

queueState - The queue state, non-null.

Returns:

True if the state represents a queue-state with server-access credits available.

isStartArmed

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

Description copied from interface: SimQueueStatePredictor

Checks whether a given state represents StartArmed on given queue.

Specified by:

isStartArmed in interface SimQueueStatePredictor<EncTL>

Parameters:

queue - The queue.

queueState - The queue state, non-null.

Returns:

True if the state represents StartArmed at given queue.

getNextQueueEventTimeBeyond

public double getNextQueueEventTimeBeyond(EncTL queue,
                                          SimQueueState<SimJob,EncTL> queueState,
                                          Set<SimEntitySimpleEventType.Member> queueEventTypes)
                                   throws SimQueuePredictionException

Description copied from interface: SimQueueEventPredictor

Returns the time and types of the next event(s) scheduled strictly beyond the time at (the state object of) a specific queue.

The time from which to search must be taken from SimQueueState.getTime(), and equals Double.NaN after initialization.

Specified by:

getNextQueueEventTimeBeyond in interface SimQueueEventPredictor<EncTL>

Overrides:

getNextQueueEventTimeBeyond in class AbstractSimQueuePredictor_Composite_Enc<EncTL>

Parameters:

queue - The queue, non-null.

queueState - The queue-state, non-null.

queueEventTypes - A non-null set to store the (possible multiple) event types; it must be cleared upon entry.

Returns:

The time of the next event, or Double.NaN if no such event exists.

Throws:

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

doWorkloadEvents_SQ_SV_ROEL_U

public void doWorkloadEvents_SQ_SV_ROEL_U(EncTL queue,
                                          WorkloadSchedule_SQ_SV_ROEL_U workloadSchedule,
                                          SimQueueState<SimJob,EncTL> queueState,
                                          Set<SimEntitySimpleEventType.Member> workloadEventTypes,
                                          Set<JobQueueVisitLog<SimJob,EncTL>> visitLogsSet)
                                   throws SimQueuePredictionException,
                                          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<EncTL>

Overrides:

doWorkloadEvents_SQ_SV_ROEL_U in class AbstractSimQueuePredictor_Composite_Enc<EncTL>

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).

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:
