        default: WARNING
    -no-id-update <boolean> (property: dontUpdateID)
        If enabled, suppresses updating the ID of data containers.
        default: false
    -padding <ZERO> (property: paddingType)
        The padding type to use.
        default: ZERO
    -inverse <boolean> (property: inverseTransform)
        If true, then the inverse transform is performed.
        default: false
    -real <boolean> (property: real)
        If enabled, the real part of the tranformation is returned.

      • getValue

        protected double getValue​(DataPoint point)
        Returns the Y-value of the DataPoint.
        Specified by:
        getValue in class AbstractFFT<Timeseries>
        point - the point to get the Y-Value from
        the Y-value
      • newDataPoint

        protected DataPoint newDataPoint​(List<DataPoint> points,
                                         int index,
                                         double y)
        Creates a new DataPoint based on the index and the new Y value. Used for padded points.
        Specified by:
        newDataPoint in class AbstractFFT<Timeseries>
        points - the original points
        index - the index of the padded point in the output data
        y - the new Y value
        the new DataPoint
