All Implemented Interfaces:
ApplicationLayer, PhysicalLayer, java.awt.event.MouseListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible
public class SimpleNetSim
extends javax.swing.JPanel
implements PhysicalLayer, ApplicationLayer, java.awt.event.MouseListener

Class SimpleNetSim is the "main" simulator class, for which reason it is a bit large. This has both the GUI and the guts of the simulator - the data structures, main loop etc. Note also that this class surrounds the basic three (transport, network, datalink) layers from above and below, which is why this class implements PhysicalLayer and ApplicationLayer. There are a couple of static methods of use, which we'll document.
