Class ClassicHistogramBuckets

Object
ClassicHistogramBuckets
All Implemented Interfaces:
Iterable<ClassicHistogramBucket>

Immutable container for histogram buckets with fixed bucket boundaries. Note that the counts are not cumulative.
  • Field Details

    • EMPTY

      public static final ClassicHistogramBuckets EMPTY
      Used in native histograms to indicate that no classic histogram buckets are present.

      public static ClassicHistogramBuckets of(List<Double> upperBounds, List<? extends Number> counts)
      To create new ClassicHistogramBuckets, you can either use one of the static of(...) methods, or use builder().

      This method will create a copy of upperBounds and counts.

      Parameters:
      upperBounds - must have the same length as counts. Must not contain duplicates. Must contain at least Double.POSITIVE_INFINITY for the +Inf bucket. An upper bound must not be Double.NaN. The upperBounds array does not need to be sorted.
      counts - must have the same length as upperBounds. The entry at index i is the count for the upperBounds at index i. For each count, Number.longValue() is called to get the value. Counts are not cumulative. Counts must not be negative.

      public static ClassicHistogramBuckets of(double[] upperBounds, Number[] counts)
      To create new ClassicHistogramBuckets, you can either use one of the static of(...) methods, or use builder().

      This method will create a copy of upperBounds and counts.

      Parameters:
      upperBounds - must have the same length as counts. Must not contain duplicates. Must contain at least Double.POSITIVE_INFINITY for the +Inf bucket. An upper bound must not be Double.NaN. The upperBounds array does not need to be sorted.
      counts - must have the same length as upperBounds. The entry at index i is the count for the upperBounds at index i. For each count, Number.longValue() is called to get the value. Counts are not cumulative. Counts must not be negative.

      public static ClassicHistogramBuckets of(double[] upperBounds, long[] counts)
      To create new ClassicHistogramBuckets, you can either use one of the static of(...) methods, or use builder().

      This method will create a copy of upperBounds and counts.

      Parameters:
      upperBounds - must have the same length as counts. Must not contain duplicates. Must contain at least Double.POSITIVE_INFINITY for the +Inf bucket. An upper bound must not be Double.NaN. The upperBounds array does not need to be sorted.
      counts - must have the same length as upperBounds. The entry at index i is the count for the upperBounds at index i. Counts are not cumulative. Counts must not be negative.
