        Replies an iterator which loop on the segment in a clockwise order from the specified start segment to the specified end segment.

        This function assumes that startSegmentConnectedByItsStart and endSegmentConnectedByItsStart parameters indicates how the segments should be connected. These values are useful to indicates how to iterate when the segment is connected to this RoadConnexion by its two ends. The semantics of the these values are:

        • true, the segment will be replied by the iterator when its start point will be found in the list;
        • false, the segment will be replied by the iterator when its end point will be found in the list;
        • null, the segment will be replied when it will be found at the first time in the list.

        The first segment replied by this function will be the startSegment or the second segment from the list, according to bountType. The last segment replied by this function will be the endSegment or the antepenulvian segment from the list, according to bountType.

        This function assumes a CoordinateSystemConstants.GIS_2D

        Parameters:
        startSegment - is the first segment to iterate.
        startSegmentConnectedByItsStart - indicates if the start segment is connected by its first point.
        endSegment - is the last segment to iterate.
        endSegmentConnectedByItsStart - indicates if the start segment is connected by its first point.
        boundType - indicates if the two given segments will be included into the iterated segment set.
        Returns:
        the iterator on segments.

        @Pure
Iterator<RoadSegment> toClockwiseIterator​(RoadSegment startSegment)
        Replies an iterator which loop on the segment in a clockwise order from the specified segment.

        The first segment replied by this function will be the startSegment or the second segment from the list, according to the default clockwhise type. Assuming that the segment candidates should be replied only once time if they are all included, the startSegment will never be replied as the last segment.

        Parameters:
        startSegment - is the first segment to iterate.
        Returns:
        an iterable data structure.
