Examples of avrora.sim.util.MulticastWatch

avrora.sim.util.MulticastWatch
The MulticastProbe is a wrapper around multiple watches that allows them to act as a single watch. It is useful for composing multiple watches into one and is used internally in the simulator. @author Ben L. Titzer @see Simulator
