      • getRange

        S getRange​(T lowerQuantile,
           T upperQuantile,
           BoundsRule boundsRule)
        This is a callback request to the data source to fill a quantiles sketch with a range of data between upper and lower bounds. Which of these bounds are to be included is determined by the BoundsRule.

        This range of data may or may not be subsequently further partitioned.

        Parameters:
        lowerQuantile - the lowest quantile of a range
        upperQuantile - the highest quantile of a range
        boundsRule - determines which quantile bounds to include
        Returns:
        a quantiles sketch filled from the given upper and lower bounds.
