Class Node

java.lang.Object

ucar.nc2.dt.ugrid.rtree.Node

All Implemented Interfaces:

Serializable

public class Node
extends Object
implements Serializable

The Node class represents a data node for an RTree. This class contains references to child nodes as polygons with associated ids NOTE: findEntry is not implemented. This is used in node deletion by the RTree.

Method Detail

expandMBR

public static LatLonRectangle2D expandMBR(LatLonRectangle2D mbr,
                                          LatLonPolygon2D poly)

Adds the given poly to mbr as if mbr were a rectangle. Neither objects are modified.

Parameters:

mbr - the minimum bounding rectangle

poly - a polygon to be fit inside the mbr

Returns:

the bounding rectangle of the union between mbr and poly as polgon2d object

expandMBR

public static LatLonRectangle2D expandMBR(LatLonRectangle2D mbr,
                                          LatLonRectangle2D rect)

Adds the given rect to mbr as if mbr were a rectangle. Neither objects are modified.

Parameters:

mbr - the minimum bounding rectangle

rect - a rectangle to be fit inside the mbr

Returns:

the bounding rectangle of the union between mbr and poly as polgon2d object

expandMBR
