This static class contains the executive of a discrete-event simulation.
It maintains the simulation clock and starts executing the events in the appropriate order. Its methods permit one to start, stop, and (re)initialize the simulation, and read the simulation clock.
Starting from SSJ-2.0, the Sim
class now uses the default simulator returned by the getDefaultSimulator()
method in the Simulator class. Although the Sim
class is perfectly adequate for simple simulations, the Simulator class is more general and supports more functionnalities. For example, if one needs to have more than one simulation clock and event list, one will have to use the Simulator class instead of the simpler Sim
class.
Gets the currently used event list.
Reinitializes the simulation executive by clearing up the event list, and resetting the simulation clock to zero.
This method must not be used to initialize process-driven simulation; umontreal.ssj.simprocs.SimProcess.init must be used instead.
◆ init() [2/2]Same as init, but also chooses evlist
as the event list to be used.
For example, calling init(new DoublyLinked())
initializes the simulation with a doubly linked linear structure for the event list. This method must not be used to initialize process-driven simulation; umontreal.ssj.simprocs.DSOLProcessSimulator(init) (EventList)
or
umontreal.ssj.simprocs.ThreadProcessSimulator(init) (EventList)
must be used instead.
This method is used by the package umontreal.ssj.simprocs; it should not be used directly by a simulation program.
It removes the first event from the event list and sets the simulation clock to its event time.
null
if there is no such event
Starts the simulation executive.
There must be at least one Event
in the event list when this method is called.
Tells the simulation executive to stop as soon as it takes control, and to return control to the program that called start.
This program will then continue executing from the instructions right after its call to Sim.start
. If an Event is currently executing (and this event has just called Sim.stop
), the executive will take control when the event terminates its execution.
Returns the current value of the simulation clock.
