getDescription

public String getDescription()

Description copied from interface: LoadFactory_SQ_SV

Returns a description of this load factory.

The default implementation returns "None provided!".

getDescription in interface LoadFactory_SQ_SV<J extends SimJob,Q extends SimQueue>

Overrides:

getDescription in class LoadFactory_SQ_SV_0010<J extends SimJob,Q extends SimQueue>

Returns:

A description of this load factory.

generate

public Set<J> generate(org.javades.jsimulation.r5.SimEventList eventList,
                       boolean attachSimJobsToEventList,
                       Q queue,
                       SimJobFactory<J,Q> jobFactory,
                       int numberOfJobs,
                       boolean reset,
                       double resetTime,
                       Set<LoadFactoryHint> hints,
                       NavigableMap<Double,Set<SimJQEvent>> queueExternalEvents)

Generates the load.

This method

• generates the job load according to LoadFactory_SQ_SV_0010.generate(org.javades.jsimulation.r5.SimEventList, boolean, Q, org.javades.jqueues.r5.entity.jq.job.SimJobFactory<J, Q>, int, boolean, double, java.util.Set<org.javades.jqueues.r5.util.loadfactory.LoadFactoryHint>, java.util.NavigableMap<java.lang.Double, java.util.Set<org.javades.jqueues.r5.entity.jq.SimJQEvent>>);
• only if the queue is a SimQueueWithGate or has SimQueueWithGateOperationUtils.GatePassageCreditsOperation registered, it adds setting the number of gate-passage credits on the queue at 11.19, 22.19, 33.19, etc.

Note: this method generates SimQueueGateEvents only for SimQueueWithGates or queues that have has SimQueueWithGateOperationUtils.GatePassageCreditsOperation registered as operation. The check is done at runtime, and not reflected in the generic-type arguments of this class. Otherwise, instances of this class behave as if they were a LoadFactory_SQ_SV_0010.

The amount of gate-passage credits is drawn from {0, 1, 5, Double.MAX_VALUE} with equal probabilities. Setting the gate-passage credits is scheduled roughly until all jobs would have been served under single-server FCFS, with an additional 100% to account for the gate delays.

Specified by:

generate in interface LoadFactory_SQ_SV<J extends SimJob,Q extends SimQueue>

Overrides:

generate in class LoadFactory_SQ_SV_0010<J extends SimJob,Q extends SimQueue>

Parameters:

eventList - The event list, non-null.

attachSimJobsToEventList - Whether or not to attach the generated SimJobs to the SimEventList; typically set to false (see SimEntity and SimJob for more details on the consequences).

queue - The queue, non-null.

jobFactory - The job factory, non-null.

numberOfJobs - The number of jobs to generate, non-negative.

reset - Whether or not to reset the event list.

resetTime - The time to which to reset the event list.

hints - An optional set of LoadFactoryHints, may be null and unknown hints are silently ignored.

queueExternalEvents - An optional map for storing the generated SimJQEvents indexed by event time and for events at the same time, by order of occurrence. The map is not cleared; generated events in this method are assumed to occur after any existing events at the same time.

Returns:

The set of jobs generated.
