- org.HdrHistogram.DoubleLogarithmicIterator
-
- All Implemented Interfaces:
java.util.Iterator<DoubleHistogramIterationValue>
public class DoubleLogarithmicIterator extends java.lang.Object implements java.util.Iterator<DoubleHistogramIterationValue>
Used for iterating throughDoubleHistogram
values values in logarithmically increasing levels. The iteration is performed in steps that start at valueUnitsInFirstBucket and increase exponentially according to logBase, terminating when all recorded histogram values are exhausted. Note that each iteration "bucket" includes values up to and including the next bucket boundary value.
