        public void addShape​(T shape)
        Add a shape to the composite.
        Parameters:
        shape - is the shape to add.

      • size

        public int size()
        Get the number of shapes in the composite
        Returns:
        the number of shapes

        public T getShape​(int index)
        Get shape at index
        Returns:

      • isWithin

        public boolean isWithin​(Vector point)
        Description copied from interface: Membership
        Check if a point is within this shape.
        Specified by:
        isWithin in interface Membership
        Parameters:
        point - is the point to check.
        Returns:
        true if the point is within this shape

      • isWithin

        public boolean isWithin​(double x,
                        double y,
                        double z)
        Description copied from interface: Membership
        Check if a point is within this shape.
        Specified by:
        isWithin in interface Membership
        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.
        Specified by:
        getEdgePoints in interface GeoShape
        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.
        Specified by:
        intersects in interface GeoShape
        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.

      • getBounds

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