Method Detail

run

public void run()

This is the animation thread's main entry point. The animation thread must setup the simulation event time line, sort the time line, and start the animation.

Specified by:

run in interface java.lang.Runnable

getPacketFlow

public java.util.Vector<java.awt.Point> getPacketFlow(int fromNode,
                                                      int toNode,
                                                      int noOfPoints)

Calculates the set of Co-ordinates at which the packet component should be drawn in the Animation.

Parameters:

fromNode - - Read from the out.nam File

toNode - - Read from the out.nam File

noOfPoints - - The number of Points between two nodes where packet needs to be drawn.

Returns:

- An Vector of Points containing the co-ordinates of the locations of packet to be drawn.

setupTimeLine

public void setupTimeLine()

Sets up the TimeLine of events that need to be animated and stores it as a Vector of TimeLine Objects.

startAnimation

public void startAnimation(int increment)

Reads the TimeLine Vector and animates pakcets.

Parameters:

increment - - Time Interval in ms for incrementing the simulation time period.

sortTimeLine

public void sortTimeLine()

Sort the TimeLine Vector using Quicksort.

drawPacket

public void drawPacket(int X,
                       int Y,
                       int packetSize)

Draw a Rectangle to represent the packet.

Parameters:

X - x co-ordinate for the Rectangle

Y - y co-ordinate for the Rectangle

packetSize - - the size of the rectangle - currently ignored

erasePacket

public void erasePacket(int X,
                        int Y,
                        int packetSize)

Erase the Rectangle at the given Location.

Parameters:

X - x co-ordinate for the Rectangle

Y - y co-ordinate for the Rectangle

packetSize - - the size of the rectangle - currently ignored
