public class Simulator
extends AbstractSimulator

This class represents a parallel DEVS simulator, in xDEVS style. The simulator is responsible for the simulation of a DEVS model, and it is composed of a simulation clock and the model to simulate. The simulator is responsible for the initialization, execution and termination of the simulation.

Method Summary

Modifier and Type	Method	Description
void	clear()	Empties the event list at the ports of the associated model.
void	deltfcn()	Executes one of the transition functions of the DEVS simulation, depending on the current state of the model and whether there are new events or not.
void	exit()	This is a special function, out of the DEVS formalism, that allows to realize some actions when the simulation ends.
Atomic	getModel()	Gets the associated model of the simulator.
void	initialize()	Initializes the simulator and the associated model.
void	lambda()	Executes the output function of the DEVS simulation.
double	ta()	Executes the time advance mechanism of the DEVS simulation.

Constructor Detail

Simulator

public Simulator(SimulationClock clock,
                 Atomic model)

Creates a new simulator with the given simulation clock and model.

Parameters:

clock - the simulation clock of the simulator.

model - the model to simulate.

Method Detail

initialize

public void initialize()

Description copied from class: AbstractSimulator

Initializes the simulator and the associated model. This is not part of the DEVS formalism, but it is a necessary step to prepare the simulator for the simulation.

Specified by:

initialize in class AbstractSimulator

exit

public void exit()

Description copied from class: AbstractSimulator

This is a special function, out of the DEVS formalism, that allows to realize some actions when the simulation ends.

Specified by:

exit in class AbstractSimulator

ta

public double ta()

Description copied from class: AbstractSimulator

Executes the time advance mechanism of the DEVS simulation.

Specified by:

ta in class AbstractSimulator

Returns:

the new DEVS sigma.

deltfcn

public void deltfcn()

Description copied from class: AbstractSimulator

Executes one of the transition functions of the DEVS simulation, depending on the current state of the model and whether there are new events or not.

Specified by:

deltfcn in class AbstractSimulator

lambda

public void lambda()

Description copied from class: AbstractSimulator

Executes the output function of the DEVS simulation.

Specified by:

lambda in class AbstractSimulator

clear

public void clear()

Description copied from class: AbstractSimulator

Empties the event list at the ports of the associated model.

Specified by:

clear in class AbstractSimulator

getModel

public Atomic getModel()

Description copied from class: AbstractSimulator

Gets the associated model of the simulator.

Specified by:

getModel in class AbstractSimulator

Returns:

the associated model of the simulator.
