            double y,
            double radius)

x

public float x()

y

public float y()

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

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

intersects

public boolean intersects(Rectangle r)

Specified by:

intersects in interface Geometry

intersects

public boolean intersects(Circle c)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

intersects

public boolean intersects(Point point)
