simu.framework.Engine

simu.model.OwnEngine

All Implemented Interfaces:

Runnable, IEngine

public class OwnEngine
extends Engine

The OwnEngine class represents the simulation engine for the restaurant simulation. It extends the Engine class and contains the main logic for the simulation. The engine manages the simulation time, event list, and the execution of events. The engine also contains the service points and the arrival process for the simulation. The engine is responsible for generating events and running the simulation. The engine also calculates performance metrics for the simulation. The engine is used by the controller to manage the simulation.

Constructor Details

OwnEngine

public OwnEngine(IControllerForM controller,
 ControllerForFxml controllerFxml,
 SettingsController settingsController)

Constructs an OwnEngine with the specified controller, controller for FXML, and settings controller. The engine also creates the service points and the arrival process for the simulation.

Parameters:

controller - the controller used to manage the simulation

controllerFxml - the controller for FXML used to manage the simulation

settingsController - the settings controller used to manage the simulation settings

Method Details

pauseSimulation

public void pauseSimulation()

Pauses the simulation.

resumeSimulation

public void resumeSimulation()

Resumes the simulation.

randChance

public int randChance(int chance)

Returns random number between 0 and chance.

Parameters:

chance -

Returns:

random number
