Package org.processmining.plugins.stochasticpetrinet.distribution.timeseries

Class StatefulTimeseriesDistribution

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.commons.math3.analysis.UnivariateFunction, org.apache.commons.math3.distribution.RealDistribution
    Direct Known Subclasses:
    ARMATimeSeries, SinusoidalSeries
    public abstract class StatefulTimeseriesDistribution
extends AnotherAbstractRealDistribution
    This is a "stateful" distribution that knows it's current time. Depending on its time, it has a value which is determined by the subclass (e.g. SinusoidalSeries)

    BEWARE: the class creating samples needs to update the current state to the sampling timestamp!

      • getCurrentSeriesValue

        protected abstract double getCurrentSeriesValue​(long currentTime)
        Sub-classes need to implement this. It returns the value of the time series model given the current time
        Parameters:
        currentTime - the current time as a POSIX timestamp (millis since 01-01-1970)
        Returns:
        double the value of the underlying series at the given point in time.
