Class SimulationScheduler

java.lang.Object
  verinec.netsim.gui.SimulationScheduler

public class SimulationScheduler
extends Object

Responsible for the animation of the events. For this reason, the class maintains two tables, one containing all the events and another for the current active events.

private int	halftime needed for Layer2Receive, to determine their start-time.
private boolean[]	layerFilter A filter to control which layers are shown.
private int	pausetime
private int	simulationend unrealistic low value, so this will be changed during initialisation.

Constructor Summary

SimulationScheduler(Element events, SimulatorThread simuThread, VerinecStudio parent)
Parses all the events and adds them to the table.

Method Summary

private void	addToTable(Element events, Vector data) Helper method to parse the testfile.
void	animateEvents(int time, int substeps) Animates all events in the table of the current active events.
void	filterEvents(boolean[] theFilter) Sets a filter for the layers.
void	loadEvents(int time) Update the events table to contain the current ones.
void	schedulepause(int time) Schedules a pause.

Field Detail

verinecStudio

private VerinecStudio verinecStudio

simuThread

private SimulatorThread simuThread

eventTable

private DefaultTableModel eventTable

activeEvents

private DefaultTableModel activeEvents

layerFilter

private boolean[] layerFilter

A filter to control which layers are shown. Only the events which value is set to true are shown: Layer5Event: layerFilter[5] Layer4Event: layerFilter[4] Layer3Event: layerFilter[3] Layer2EventMac: layerFilter[2] Layer2EventSend: layerFilter[1] Layer2EventReceive: layerFilter[1] layerFilter[0] would be for events on hardware layer, which is currently not simulated.

simulationstart

private int simulationstart

unrealistic high value, so this will be changed during initialisation.

simulationend

private int simulationend

unrealistic low value, so this will be changed during initialisation.

halftime

private int halftime

needed for Layer2Receive, to determine their start-time.

pausetime

private int pausetime

Constructor Detail

SimulationScheduler

public SimulationScheduler(Element events,
                           SimulatorThread simuThread,
                           VerinecStudio parent)
                    throws SimulationException

Parses all the events and adds them to the table.

Parameters:

events - the whole testfile.

simuThread - the owner of the Scheduler.

parent - A reference to the main application window.

Throws:

SimulationException - When a network component can not be found on the panel.

Method Detail

addToTable

private void addToTable(Element events,
                        Vector data)
                 throws SimulationException

Helper method to parse the testfile. Extracts the events recursively.

Parameters:

events - the current events

data - the ancient events

Throws:

SimulationException - when a networkcomponent could not be found on the panel.

schedulepause

public void schedulepause(int time)

Schedules a pause. (needed by the step buttons).

Parameters:

time - the time when the pause shall occur.

animateEvents

public void animateEvents(int time,
                          int substeps)

Animates all events in the table of the current active events.

Parameters:

time - the current simulation time.

substeps - the current substeps.

loadEvents

public void loadEvents(int time)

Update the events table to contain the current ones. Removes all the events which reached their end time from the table of the active events. Adds the new events which occur at the current time to the table.

Parameters:

time - The time to load events for.

filterEvents

public void filterEvents(boolean[] theFilter)

Sets a filter for the layers.

Parameters:

theFilter - the desired layers.

layerFilter

terminateSimulation

public void terminateSimulation()

Removes the filterpanel from the sidewindow when the simulation is terminated.
