ikr.simlib.meters.time.MedianTimeMeter

public class MedianTimeMeter
extends TimeMeter

MedianTimeMeter uses a median statistic of type StdMedianStatistic to collect the time interval data. If the parameter maxBufferSize is set to zero, all samples will be stored internally and the median will be calculated at the end of the simulation. Since this is very memory consuming, maxBufferSize can be set to a number > 0, which determines the maximum number of samples the statistic should hold in memory. The median is then calculated at the end of the simulation as an approximation that is based on all samples. Often, 10000 samples are sufficient for a good approximation.
