        Returns:
        the radius.
      • getCenter

      • isWithin

        public boolean isWithin​(double x,
                                double y,
                                double z)
        Description copied from interface: Membership
        Check if a point is within this shape.
        Parameters:
        x - is x coordinate of point to check.
        y - is y coordinate of point to check.
        z - is z coordinate of point to check.
        Returns:
        true if the point is within this shape
      • getEdgePoints

        public GeoPoint[] getEdgePoints()
        Description copied from interface: GeoShape
        Return a sample point that is on the outside edge/boundary of the shape.
        Returns:
        samples of all edge points from distinct edge sections. Typically one point is returned, but zero or two are also possible.
      • intersects

        public boolean intersects​(Plane p,
                                  GeoPoint[] notablePoints,
                                  Membership... bounds)
        Description copied from interface: GeoShape
        Assess whether a plane, within the provided bounds, intersects with the shape's edges. Any overlap, even a single point, is considered to be an intersection. Note well that this method is allowed to return "true" if there are internal edges of a composite shape which intersect the plane. Doing this can cause getRelationship() for most GeoBBox shapes to return OVERLAPS rather than the more correct CONTAINS, but that cannot be helped for some complex shapes that are built out of overlapping parts.
        Parameters:
        p - is the plane to assess for intersection with the shape's edges or bounding curves.
        notablePoints - represents the intersections of the plane with the supplied bounds. These are used to disambiguate when two planes are identical and it needs to be determined whether any points exist that fulfill all the bounds.
        bounds - are a set of bounds that define an area that an intersection must be within in order to qualify (provided by a GeoArea).
        Returns:
        true if there's such an intersection, false if not.
      • intersects

        public boolean intersects​(GeoShape geoShape)
        Description copied from interface: GeoAreaShape
        Assess whether a shape intersects with any of the edges of this shape. Note well that this method must return false if the shape contains or is disjoint with the given shape. It is permissible to return true if the shape is within the specified shape, if it is difficult to compute intersection with edges.
        Parameters:
        geoShape - is the shape to assess for intersection with this shape's edges.
        Returns:
        true if there's such an intersection, false if not.
      • getBounds

        public void getBounds​(Bounds bounds)
        Description copied from interface: Bounded
        Compute bounds for the shape.
        Specified by:
        getBounds in interface Bounded
        Overrides:
        getBounds in class GeoBaseBounds
        Parameters:
        bounds - is the input bounds object. The input object will be modified.
      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object
