Method Detail

pause

public static void pause(int milliseconds)

broadcastZero

public void broadcastZero()
                   throws CollisionException

Turn the light system on (if it isn't already), then wait half a period. Then turn the light off, for half a period.

Throws:

CollisionException

broadcastOne

public void broadcastOne()
                  throws CollisionException

Turn the light system off (if it isn't already), then wait half a period. Then turn the light on, for half a period.

Throws:

CollisionException

broadcast

public void broadcast(java.lang.String bits)
               throws CollisionException

Given a string of bits (0s and 1s), send each bit using broadcastOne/Zero(). Build up a string of successfully sent bits (called "broadcasted"). Switch the light off when done.

Throws:

CollisionException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Thread

run

public void run()

Repeatedly (and as fast as possible), check if the panel's light has changed from on to off or vice versa. When it does, check how much time passed between transitions. Based on this time and which direction the transition was made, determine if a 0 or 1 bit was received. Send the result off to the registered Listener.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread

setListener

public void setListener(BitListener l)

isSilent

public boolean isSilent()

getID

public int getID()
