Class EmuWorld

java.lang.Object
  edu.cmu.emulator.world.EmuWorld

All Implemented Interfaces:

Runnable

public class EmuWorld
extends Object
implements Runnable

EmuWorld emulates the virtual world through which emulated nodes are moving. It deals with node movement alone. Also implements the methods which are invoked by the Event model. This class does not deal with issues such as traffic. We allocate emuNodes during emulator initialization, and never allow it to change. We also do not allow node definitions to change. I.e. nodes can never change the number of antennas they have etc. This allows some mutual exclusion simplifications.

Constructor Detail

EmuWorld

public EmuWorld(EmuNode[] emuNodes,
                Emulator emulator,
                WorldDef worldDef)

Parameters:

emuNodes - All nodes that will ever be used in the emulation. Since this array will never change during the course of emulation, it can be accessed in a thread-safe manner.

Method Detail

initNodes

protected void initNodes()

init

public void init()

start

public void start()

run

public void run()

Specified by:

run in interface Runnable

addNode

public void addNode(String nodeName,
                    double[] pos)

setPos

public void setPos(String nodeName,
                   double[] pos)

setOrientation

public void setOrientation(String nodeName,
                           double[][] orientation)

startRoute

public void startRoute(String nodeName,
                       String routeName)

stop

public void stop()

getNodeIndex

public int getNodeIndex(EmuNode node)

getNodeIndex

public int getNodeIndex(String nodeName)

Thread-safe by virtue of the fact that emuNodes never changes during emulation.

getNode

public EmuNode getNode(String name)

getNode

public EmuNode getNode(int index)

getEmuNodeNames

public String[] getEmuNodeNames()

getNumNodes

public int getNumNodes()

getWorldDef
