Examples of org.modeshape.jcr.api.monitor.Statistics

org.modeshape.jcr.api.monitor.Statistics
The immutable statistics for a sample of values. The statistics include the {@link #getMinimum() minimum}, {@link #getMaximum() maximum}, {@link #getMean() mean (average)}, {@link #getVariance() variance} and{@link #getStandardDeviation() standard deviation}.
The median value is not included in these statistics, since the median value cannot be rolled up given a series of statistics without having the original values. It is possible to compute the weighted median, but this loses effectiveness/value the more times it is rolled up.
@since 3.0

                seconds[currentSecond++] = stats;
                if (currentSecond == MAX_SECONDS) {
                    // The we've finished filling the seconds, so reset the index
                    // and roll the seconds statistics into a new cumulative statistic for the last minute ...
                    currentSecond = 0;
                    Statistics cumulative = statisticsFor(seconds);
                    minutes[currentMinute++] = cumulative;
                    if (currentMinute == MAX_MINUTES) {
                        // The we've finished filling the minutes, so reset the index
                        // and roll the minutes statistics into a new cumulative statistic for the last hour ...
                        currentMinute = 0;
