umontreal.iro.lecuyer.simevents.Simulator

umontreal.iro.lecuyer.simprocs.ProcessSimulator

umontreal.iro.lecuyer.simprocs.ThreadProcessSimulator

public class ThreadProcessSimulator
extends ProcessSimulator

Represents a process simulator using Java threads for process synchronization. The simulation process threads are synchronized so only one process runs at a time.

Method Summary

Modifier and Type	Method and Description
umontreal.iro.lecuyer.simprocs.SimThread	createControlEvent(SimProcess process) Constructs and returns a new Event object used for synchronization.
void	delay(SimProcess process, double delay) Suspends the execution of process and schedules it to resume its execution in delay units of simulation time.
void	init() Initializes the thread process-driven simulation using SplayTree algorithm as EventList.
void	init(EventList evlist) Initializes the thread process-driven simulation using evlist variable as EventList.
void	kill(SimProcess process) Terminates the life of process and sets its state to DEAD, after canceling its control event if there is one.
void	killAll() Kills all threads linked to the current variable.
void	suspend(SimProcess process) Suspends process.

Constructor Detail

ThreadProcessSimulator

public ThreadProcessSimulator()

Creates a new ThreadProcessSimulator variable.

Method Detail

init

public void init()

Initializes the thread process-driven simulation using SplayTree algorithm as EventList. This kills all processes already associated with the current variable.

Overrides:

init in class Simulator

init

public void init(EventList evlist)

Initializes the thread process-driven simulation using evlist variable as EventList. This kills all processes already associated with the current variable.

Overrides:

init in class Simulator

Parameters:

evlist - EventList assigned to the current variable eventlist field

createControlEvent

public umontreal.iro.lecuyer.simprocs.SimThread createControlEvent(SimProcess process)

Description copied from class: ProcessSimulator

Constructs and returns a new Event object used for synchronization. Such control events are used by process simulator to start a process or to resume it if it is already started.

Specified by:

createControlEvent in class ProcessSimulator

delay

public void delay(SimProcess process,
                  double delay)

Description copied from class: ProcessSimulator

Suspends the execution of process and schedules it to resume its execution in delay units of simulation time. The state of the process also changes to DELAYED.

Specified by:

delay in class ProcessSimulator

Parameters:

process - SimProcess variable to delay.

delay - delay value, in simulation time units.

suspend

public void suspend(SimProcess process)

Description copied from class: ProcessSimulator

Suspends process. If the process is EXECUTING, this suspends its execution. If the process is DELAYED, this cancels its control event. This method also places the process in the SUSPENDED state.

Specified by:

suspend in class ProcessSimulator

Parameters:

process - SimProcess variable to suspend.

kill

public void kill(SimProcess process)

Description copied from class: ProcessSimulator

Terminates the life of process and sets its state to DEAD, after canceling its control event if there is one.

Specified by:

kill in class ProcessSimulator

killAll

public void killAll()

Kills all threads linked to the current variable.

Specified by:

killAll in class ProcessSimulator
