      protected AbstractSolarActivityData(String supportedNames, D loader, DataProvidersManager dataProvidersManager, TimeScale utc, int maxSlots, double maxSpan, double maxInterval, double minimumStep)
      Constructor.
      Parameters:
      supportedNames - regular expression for supported AGI/CSSI space weather files names
      loader - data loader
      dataProvidersManager - provides access to auxiliary data files.
      utc - UTC time scale
      maxSlots - maximum number of independent cached time slots in the time-stamped cache
      maxSpan - maximum duration span in seconds of one slot in the time-stamped cache
      maxInterval - time interval above which a new slot is created in the time-stamped cache
      minimumStep - overriding minimum step designed for non-homogeneous tabulated values. To be used for example when caching monthly tabulated values. May be null.

    • getLinearInterpolation

      protected double getLinearInterpolation(AbsoluteDate date, Function<L,Double> solarActivityToDoubleMapper)
      Performs a linear interpolation between two values The weights are computed from the time delta between previous date, current date, next date.
      Parameters:
      date - current date
      solarActivityToDoubleMapper - mapping function taking solar activity as input and returning a double
      Returns:
      the value interpolated for the current date

    • getLinearInterpolation

      protected double getLinearInterpolation(AbstractSolarActivityData<L,D>.LocalSolarActivity localSolarActivity, Function<L,Double> solarActivityToDoubleMapper)
      Performs a linear interpolation between two values The weights are computed from the time delta between previous date, current date, next date.
      Parameters:
      localSolarActivity - solar activity around current date
      solarActivityToDoubleMapper - mapping function taking solar activity as input and returning a double
      Returns:
      the value interpolated for the current date
