      verinec.netsim.gui.SimulatorThread

All Implemented Interfaces:

Runnable

public class SimulatorThread
extends Thread

This thread is responsible for animating the simulation. Calls the animate methode of the events in well defined time intervals. It also manages a time subunit and when this subunit reaches a defined value, the progressbar of the Toolbar will be updated. If the environment variable verinec.netsim.loop is set, the simulation loops endlessly instead of stopping when the last step has been reached.

Constructor Detail

SimulatorThread

public SimulatorThread(Element events,
                       int initSpeed,
                       SimulationToolbar toolbar,
                       VerinecStudio parent)
                throws SimulationException

Initalizes the thread and creates a scheduler for the events.

Parameters:

events - The whole testfile.

initSpeed - The current speed.

toolbar - A reference to the toolbar. (needed to perform updates to the progressbar)

parent - A reference to the main application window.

Throws:

SimulationException - When a network ressource cannot be found or the events are invalid.

Method Detail

setSimulationBoundaries

public void setSimulationBoundaries(int start,
                                    int end)

Set start and stop time of the simulation.

Parameters:

start - the startvalue.

end - the endvalue.

playSimulation

public void playSimulation()

Launches the thread.

wakeup

private void wakeup()

Wakes up the sleeping thread.

pauseSimulation

public void pauseSimulation()

Pauses the simulation.

stopSimulation

public void stopSimulation()

Stops the simulation.

stepForward

public void stepForward()

Jumps one time unit forward and animates the steps. Afterwards, a pause is scheduled.

stepBackward

public void stepBackward()

Jumps one time unit backward and animates the steps. Afterward, a pause is scheduled.

setSpeed

public void setSpeed(int value)

Changes the simulationspeed.

Parameters:

value - the new speed of the simulation.

progress

public void progress(int time)

Loads the new events to the panel.

Parameters:

time - The time point to load events for.

terminateSimulation

public void terminateSimulation()

Terminates the simulation, that is set running=false, stop the simulation and notify the scheduler.

run

public void run()

Animates in every slope the events. Also updates the progressbar when necessary. Also responsible to animate the simulation at the same real time speed on every machine.

run in interface Runnable

run in class Thread
