Uses of EstimatedHistogram in org.apache.cassandra.utils

Methods in org.apache.cassandra.utils that return EstimatedHistogram

Modifier and Type	Method	Description
EstimatedHistogram	HistogramBuilder.buildWithStdevRangesAroundMean()	See HistogramBuilder.buildWithStdevRangesAroundMean(int)
EstimatedHistogram	HistogramBuilder.buildWithStdevRangesAroundMean(int maxdevs)	Calculate the min, mean, max and standard deviation of the items in the builder, and generate an EstimatedHistogram with upto maxdev stdev size ranges either side of the mean, until min/max are hit; if either min/max are not reached a further range is inserted at the relevant ends.
