Interface Geometry

All Known Implementing Classes:

Circle, Point, Rectangle

public interface Geometry

A geometrical region that represents an Entry spatially. It is recommended that implementations of this interface implement equals() and hashCode() appropriately that entry equality checks work as expected.

Modifier and Type	Method and Description
double	distance(Rectangle r) Returns the distance to the given Rectangle.
boolean	intersects(Rectangle r)
Rectangle	mbr() Returns the minimum bounding rectangle of this geometry.

Method Detail

distance

double distance(Rectangle r)

Returns the distance to the given Rectangle. For a Rectangle this might be Euclidean distance but for an EPSG4326 lat-long Rectangle might be great-circle distance. The distance function should satisfy the following properties:

distance(r) >= 0

if r1 contains r2 then distance(r1)<=distance(r2)

Parameters:

r - rectangle to measure distance to

Returns:

distance to the rectangle r from the geometry

mbr

Rectangle mbr()

Returns the minimum bounding rectangle of this geometry.

Returns:

minimum bounding rectangle

intersects

boolean intersects(Rectangle r)
