Constructor Detail

Simulator

public Simulator()

constructs Simulator object, and load simulator configuration

Method Detail

getInstance

public static Simulator getInstance()

gets the singleton instance of simulator

Returns:

the singleton instance of simulator

initLog

public void initLog()

initializes logs

pauseIt

public void pauseIt()

pauses simulation

resumeIt

public void resumeIt()

resumes paused simulation

stopIt

public void stopIt()

terminates current simulation

start

public void start()

starts a new simulation

GUIstart

public void GUIstart()

starts a new simulation, to be called from GUI

init

public void init()

reads graph file, generate graph object, initialize log, and configure topology

loadSimulatorConf

public void loadSimulatorConf()

loads simulation properties from configure file

GUIinit

public void GUIinit()

initializes log, and configure topology. in GUI mode, graph object should already be created by then

confTopology

public void confTopology()

generates topology from graph file

confProtocol

public void confProtocol(Protocol p)

configures a specific protocol using virtual function.(factory patton)

cleanup

public void cleanup()

closes log files and calculate total running time

getProperties

public java.util.Properties getProperties()

gets simulator properties

handle

public boolean handle(SimEvent e)

handles simulator level event. simulation start and end events

Specified by:

handle in interface SimEventHandler

Parameters:

e - the event to be handled

Returns:

true if already handled

setPP

public void setPP(ProtocolPanel p)

sets protocolpanel, the handle to GUI, for GUI purpose

getPP

public ProtocolPanel getPP()

gets protocolpanel

setEnd

public void setEnd(int e)

set end time, so that GUI can calculate finished percentage

reset

public void reset()

stop current simulation, reset simulator

main

public static void main(java.lang.String[] args)

main simulator function
