Class PercentileIterator

  • All Implemented Interfaces:
    Iterator<HistogramIterationValue>
    public class PercentileIterator
extends Object
implements Iterator<HistogramIterationValue>
    Used for iterating through histogram 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.

    • Constructor Detail

      • PercentileIterator

        public PercentileIterator​(AbstractHistogram histogram,
                          int percentileTicksPerHalfDistance)
        Parameters:
        histogram - The histogram this iterator will operate on
        percentileTicksPerHalfDistance - The number of equal-sized iteration steps per half-distance to 100%.

    • Method Detail

      • reset

        public void reset​(int percentileTicksPerHalfDistance)
        Reset iterator for re-use in a fresh iteration over the same histogram data set.
        Parameters:
        percentileTicksPerHalfDistance - The number of iteration steps per half-distance to 100%.

      • hasNext

        public boolean hasNext()
        Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)
        Specified by:
        hasNext in interface Iterator<HistogramIterationValue>
        Returns:
        true if the iterator has more elements.
