      • addValue

        public void addValue​(int timestep,
                     double value)
        Adds a timestep-value pair to the this time series. It is assumed that the given timestep is larger than any other before, so that at the end it holds: t_i < t_j for i < j.
        Parameters:
        timestep - The timestep for which a value will be added
        value - The value of the timestep

      • getValueOrNull

        public java.lang.Double getValueOrNull​(int timestep)
        Returns the value of the given timestep if one exists, null otherwise.
        Parameters:
        timestep - The timestep to get the value for
        Returns:
        The value of the given timestep if one exists, otherwise null.

      • getWindowedTimeSeries

        public SensorTimeSeries getWindowedTimeSeries​(int fromTimestep,
                                              int toTimestep)
        Returns a part of this time series starting at the given fromTimestep and ending at the given toTimestep excluding.
        Parameters:
        fromTimestep - The starting point of the window
        toTimestep - The ending point of the window (exclusive)
        Returns:
        A window of this SensorTimeSeries
