Shouldn't we stick to names used by the JDK whenever the semantics is identical?

{code}
StorelessUnivariateStatistic add(double d);
{code}

What's the intended usage?
With the {{addAll}} methods, the API is not minimal (for a
{{StorelessStatistics}}): Processing of an array could be delegated to factory
methods defined in implementations. For example:
{code}
final Min stat = Min.of(1.2, 3.4, -5.6);
final double[] a = {-2.3, -0.1, 3.2, 4.3};
stat.combine(Min.of(a));
{code}

> Jira ticket to track the implementation of the Univariate statistics required
> for the updated SummaryStatistics API.
> The implementation would be "storeless". It should be used for calculating
> statistics that can be computed in one pass through the data without storing
> the sample values.
> Currently I have the definition of API as (this might evolve as I continue
> working)
> {code:java}
> public interface StorelessUnivariateStatistic extends DoubleConsumer,
> DoubleSupplier {
> StorelessUnivariateStatistic add(double d);
> StorelessUnivariateStatistic addAll(double[] values);
> StorelessUnivariateStatistic addAll(double[] values, int start, int
> length);
> long getN();
> void combine(StorelessUnivariateStatistic other);
> } {code}
