      • createPath

        public java.util.Optional<javafx.scene.shape.Path> createPath​(INavigableVessel vessel,
                                                              java.util.List<javafx.geometry.Point2D> pointedPath,
                                                              double scale)
        Create a path shape out of a list of points. When the path is created the vessel will be added to the TravellingVessels container.
        Specified by:
        createPath in interface IPathConverter
        Parameters:
        vessel - vessel that is traveling the path.
        pointedPath - input points.
        scale - scaling that is used on the path due to the sacle of the map.
        Returns:
        shape representing a path.

      • reduceLinePoints

        public java.util.List<javafx.geometry.Point2D> reduceLinePoints​(java.util.List<javafx.geometry.Point2D> initialPoints)
        Reduce the number of points that are needed to describe the path. No actual reduction of points happens.
        Specified by:
        reduceLinePoints in interface IPathConverter
        Parameters:
        initialPoints - list of initial points
        Returns:
        List of points

      • calculateDuration

        public long calculateDuration​(INavigableVessel vessel,
                              PathInterpolator interpolator,
                              double fraction)
        No real implementation here.
        Specified by:
        calculateDuration in interface IPathConverter
        Parameters:
        vessel - that is traveling
        interpolator - used to hold the path information
        fraction - value between [0,1]. 1 means that the whole distance is traveled.
        Returns:
        calculated travel duration.
