Method Detail

create

public static LineDouble create(double x1,
                                double y1,
                                double x2,
                                double y2)

distance

public double distance(Rectangle r)

Description copied from interface: Geometry

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)

Specified by:

distance in interface Geometry

Parameters:

r - rectangle to measure distance to

Returns:

distance to the rectangle r from the geometry

mbr

public Rectangle mbr()

Description copied from interface: Geometry

Returns the minimum bounding rectangle of this geometry.

Specified by:

mbr in interface Geometry

Returns:

minimum bounding rectangle
