      public final void record(double amount)
      Description copied from interface: DistributionSummary

    • takeSnapshot

      public HistogramSnapshot takeSnapshot()

      takeSnapshot in interface HistogramSupport
      Returns:
      A snapshot of all distribution statistics at a point in time.
