Examples of org.radargun.stats.representation.Percentile

org.radargun.stats.representation.Percentile
Representation used for retrieving value with certain percentile of occurence, e.g. for data set 1, 1, 1, 2, 3 and percentile = 60 the responseTimeMax should be 1 (as 60 % of the data set are <= 1) and for percentile 70 it is 2. It is expected that when calling {@link org.radargun.stats.OperationStats#getRepresentation(Class,Object)}with Percentile as the class argument, first argument is double value between 0 and 1 (inclusive). @author Radim Vansa <rvansa@redhat.com>
