    • calculate

      public Quantity calculate(List<Quantity> orderedValues)
      Description copied from interface: Statistic
      Compute the statistic from the List of Quantity instances. By default the List of samples is not assumed to be in any particular order. However, any Statistic subclass may implement the marker interface OrderedStatistic indicating a requirement to be provided with samples that are sorted from smallest to largest. In all cases the samples are required to be unified into the same unit (or no unit).
      Specified by:
      calculate in interface Statistic
      Parameters:
      orderedValues - List of samples Quantity instances.
      Returns:
      Computed statistic Quantity instance.

    • calculateAggregations

      public Quantity calculateAggregations(List<AggregatedData> aggregations)
      Description copied from interface: Statistic
      Compute the statistic from the List of AggregatedData instances. By default the List of samples is not assumed to be in any particular order. However, any Statistic subclass may implement the marker interface OrderedStatistic indicating a requirement to be provided with samples that are sorted from smallest to largest. In all cases the samples are required to be unified into the same unit (or no unit).
      Specified by:
      calculateAggregations in interface Statistic
      Parameters:
      aggregations - Aggregations to combine.
      Returns:
      Computed statistic value.

    • hashCode

      Overrides:
      hashCode in class BaseStatistic

    • equals

      public boolean equals(Object o)
      Overrides:
      equals in class BaseStatistic
