      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      double[] durationFrom​(AbsoluteDate[] datesForDuration)
      Get array with durations between instances dates and corresponding given dates If instance dates = [date1, date2, ..., daten] and argument datesForDuration = [d1, d2, ..., dn] then this function will return [date1 durationFrom d1, date2 durationFrom d2, ..., daten durationFrom dn].
      AbsoluteDate[] getDates()
      Get instance dates array.
      double[][] multipleDurationFrom​(AbsoluteDate[] datesForDuration)
      Get array with durations between instances dates and given dates If instance dates = [date1, date2, ..., daten] and argument datesForDuration = [d1, d2, ..., dn] then this function will return a matrix [[date1 durationFrom d1, date1 durationFrom d2, ..., date1 durationFrom dn], [date2 durationFrom d1, date2 durationFrom d2, ..., date2 durationFrom dn], [...] [daten durationFrom d1, daten durationFrom d2, ..., date1 durationFrom dn]].
      AbsoluteDate[][] multipleShiftedBy​(double[] dts)
      Get time-shifted dates for several dates or several time shifts.
      AbsoluteDate[] shiftedBy​(double[] dts)
      Get time-shifted dates for several dates and corresponding time shifts.

    • Constructor Detail

      • AbsoluteDateArrayHandling

        public AbsoluteDateArrayHandling​(AbsoluteDate[] dates)
        Simple constructor.
        Parameters:
        dates - is an array of absolute dates on which we want to apply time shift or compute duration

    • Method Detail

      • getDates

        public AbsoluteDate[] getDates()
        Get instance dates array.
        Returns:
        dates array

      • multipleShiftedBy

        public AbsoluteDate[][] multipleShiftedBy​(double[] dts)
        Get time-shifted dates for several dates or several time shifts. If instance dates = [date1, date2, ..., daten] and argument dts = [dts1, dts2, ..., dtsn] then this function will return a matrix [[date1 shiftedby dts1, date1 shiftedBy dts2, ..., date1 shiftedBy dtsn], [date2 shiftedby dts1, date2 shiftedBy dts2, ..., date2 shiftedBy dtsn], [...] [daten shiftedby dts1, daten shiftedBy dts2, ..., date1 shiftedBy dtsn]]. If ones want to apply only 1 time shift corresponding to 1 date see shiftedBy(double[]).
        Parameters:
        dts - time shifts array in seconds we want to apply to dates
        Returns:
        a matrix of new dates, shifted with respect to wanted time shifts. If instance dates = [date1, date2, ..., daten] each line correspond to one date (for example date1 shiftedBy all timeshifts (building the different columns))

      • shiftedBy

        public AbsoluteDate[] shiftedBy​(double[] dts)
        Get time-shifted dates for several dates and corresponding time shifts. If instance dates = [date1, date2, ..., daten] and argument dts = [dts1, dts2, ..., dtsn] then this function will return [date1 shiftedby dts1, date2 shiftedBy dts2, ..., daten shiftedBy dtsn]. If several time shift want to be applied on each date see multipleShiftedBy(double[]).
        Parameters:
        dts - time shifts array in seconds we want to apply to corresponding dates. Warning, must be same length as dates.
        Returns:
        an 1D array of new dates, shifted with respect to wanted corresponding time shifts.

      • multipleDurationFrom

        public double[][] multipleDurationFrom​(AbsoluteDate[] datesForDuration)
        Get array with durations between instances dates and given dates If instance dates = [date1, date2, ..., daten] and argument datesForDuration = [d1, d2, ..., dn] then this function will return a matrix [[date1 durationFrom d1, date1 durationFrom d2, ..., date1 durationFrom dn], [date2 durationFrom d1, date2 durationFrom d2, ..., date2 durationFrom dn], [...] [daten durationFrom d1, daten durationFrom d2, ..., date1 durationFrom dn]]. If ones want to compute duration from only 1 date corresponding to 1 instance date see durationFrom(AbsoluteDate[]).
        Parameters:
        datesForDuration - dates for which we want to compute the duration form instances dates
        Returns:
        a matrix of double representing durations from instance dates If instance dates = [date1, date2, ..., daten] each line correspond to one date (for example date1 duration from all given dates in arguments (building the different columns))

      • durationFrom

        public double[] durationFrom​(AbsoluteDate[] datesForDuration)
        Get array with durations between instances dates and corresponding given dates If instance dates = [date1, date2, ..., daten] and argument datesForDuration = [d1, d2, ..., dn] then this function will return [date1 durationFrom d1, date2 durationFrom d2, ..., daten durationFrom dn]. If duration from from all arguments dates wants to be compute on each date see multipleDurationFrom(AbsoluteDate[]).
        Parameters:
        datesForDuration - dates for which we want to compute the duration form instances dates. Warning must have same length as instance dates.
        Returns:
        a array of double representing durations between instance dates and corresponding argument dates
