Examples of rinde.sim.core.TimeLapse

rinde.sim.core.TimeLapse
Represents a consumable interval of time: [start, end). Instances of time lapse are handed out by the {@link Simulator} and can be received byimplementing the {@link TickListener} interface. @author Rinde van Lon (rinde.vanlon@cs.kuleuven.be)
