Class DoubleLogarithmicIterator

  • All Implemented Interfaces:
    java.util.Iterator<DoubleHistogramIterationValue>

    public class DoubleLogarithmicIterator
    extends java.lang.Object
    implements java.util.Iterator<DoubleHistogramIterationValue>
    Used for iterating through DoubleHistogram 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.

      • DoubleLogarithmicIterator

        public DoubleLogarithmicIterator​(DoubleHistogram histogram,
                                         double valueUnitsInFirstBucket,
                                         double logBase)
        Parameters:
        histogram - The histogram this iterator will operate on
        valueUnitsInFirstBucket - the size (in value units) of the first value bucket step
        logBase - the multiplier by which the bucket size is expanded in each iteration step.

      • reset

        public void reset​(double valueUnitsInFirstBucket,
                          double logBase)
        Reset iterator for re-use in a fresh iteration over the same histogram data set.
        Parameters:
        valueUnitsInFirstBucket - the size (in value units) of the first value bucket step
        logBase - the multiplier by which the bucket size is expanded in each iteration step.
