Examples of avrora.sim.SimulatorThread

avrora.sim.SimulatorThread
The SimulatorThread class is a thread intended to run a Simulator in a multiple-node simulation. The mapping is one-to-one: each simulator is expected to be run in its own thread. Multiple simulators are then synchronized by being inserted into a group using the GlobalClock class. @author Ben L. Titzer
