public class SimulationDriver

extends LogReaderDriver

A SimulationDriver simulates a sensor hardware driver by generating Measurments read from an XML log file. The Measurements generated with the same relative timing in which they appear in the given log, only with current timestamps. For example, if the timestamps in the log are 3, 5, and 9 and a simulation is started at time 50 then the simulation will generate these measurements with timestamps set to 50, 52 (50+(5-3)), and 56 (50+(9-3)). Because relaitve time is what matters, log timestamps of 100, 102, and 106 would also be generated at time 50, 52, and 56 in a simulation started at time 50.
