Class DoublePercentileIterator

java.lang.Object

org.HdrHistogram.DoublePercentileIterator

All Implemented Interfaces:

java.util.Iterator<DoubleHistogramIterationValue>

public class DoublePercentileIterator
extends java.lang.Object
implements java.util.Iterator<DoubleHistogramIterationValue>

Used for iterating through DoubleHistogram values values according to percentile levels. The iteration is performed in steps that start at 0% and reduce their distance to 100% according to the percentileTicksPerHalfDistance parameter, ultimately reaching 100% when all recorded histogram values are exhausted.
