Class SwitchLightPanel

java.lang.Object

java.lang.Thread

SwitchLightPanel

All Implemented Interfaces:

java.lang.Runnable

public class SwitchLightPanel
extends java.lang.Thread

This class is similar to a LightPanel. It connects to a LightSystem using a socket, and receives the High and Low signals going by. It sets its own local variable "isHigh" according to the state of the LightSystem "voltages". All this is done by a thread that is launched by the class constructor. Other classes, like a SwitchDisplay, can monitor this class's isHigh variable to see the state of the "wire".

This is almost identical to a LightPanel, except we won't be writing out anything to the socket. We'll just be listening in so that we can update the SwitchDisplay's little flashing lights.
