        Description copied from interface: GeoDistance
        Compute this shape's internal "distance" to the GeoPoint. Implementations should clarify how this is computed when it's non-obvious. A return value of Double.POSITIVE_INFINITY should be returned for points outside of the shape.
        Specified by:
        computeDistance in interface GeoDistance
        Parameters:
        distanceStyle - is the distance style.
        point - is the point to compute the distance to.
        Returns:
        the distance.

                                      double z)
        Description copied from interface: GeoDistance
        Compute this shape's internal "distance" to the GeoPoint. Implementations should clarify how this is computed when it's non-obvious. A return value of Double.POSITIVE_INFINITY should be returned for points outside of the shape.
        Specified by:
        computeDistance in interface GeoDistance
        Parameters:
        distanceStyle - is the distance style.
        x - is the point's unit x coordinate (using U.S. convention).
        y - is the point's unit y coordinate (using U.S. convention).
        z - is the point's unit z coordinate (using U.S. convention).
        Returns:
        the distance.

        Called by a computeDistance method if X/Y/Z is within this shape.
      • computeDeltaDistance

        public double computeDeltaDistance​(DistanceStyle distanceStyle,
                                           GeoPoint point)
        Description copied from interface: GeoDistance
        Compute the shape's delta distance given a point. This is defined as the distance that someone traveling the "length" of the shape would have to go out of their way to include the point. For some shapes, e.g. paths, this makes perfect sense. For other shapes, e.g. circles, the "length" of the shape is zero, and the delta is computed as the distance from the center to the point and back. A return value of Double.POSITIVE_INFINITY should be returned for points outside of the shape.
        Specified by:
        computeDeltaDistance in interface GeoDistance
        Parameters:
        distanceStyle - is the distance style.
        point - is the point to compute the distance to.
        Returns:
        the distance.

        Description copied from interface: GeoDistanceShape
        Compute a bound based on a provided distance measure. This method takes an input distance and distance metric and provides bounds on the shape if reduced to match that distance. The method is allowed to return bounds that are larger than the distance would indicate, but never smaller.
        Specified by:
        getDistanceBounds in interface GeoDistanceShape
        Parameters:
        bounds - is the bounds object to update.
        distanceStyle - describes the type of distance metric provided.
        distanceValue - is the distance metric to use. It is presumed that the distance metric was produced with the same distance style as is provided to this method.
