Method Detail

init

protected void init(Geo[] region)

Works by computing the centroid, then finding the largest radius. This will not, in general, produce the minimal bounding circle.

init

protected void init(GeoArray region)

Works by computing the centroid, then finding the largest radius. This will not, in general, produce the minimal bounding circle.

init

protected void init(Geo center,
                    double radius)

getCenter

public final Geo getCenter()

Description copied from interface: BoundingCircle

Returns a Geo representing the center of the circle.

Specified by:

getCenter in interface BoundingCircle

Returns:

Geo

getRadius

public final double getRadius()

Specified by:

getRadius in interface BoundingCircle

Returns:

the radius of the bounding circle in radians.

intersects

public boolean intersects(BoundingCircle bc)

Specified by:

intersects in interface BoundingCircle

Returns:

whether this bounding circle intersects with another.

intersects

public boolean intersects(Geo g,
                          double r)

Specified by:

intersects in interface BoundingCircle

Returns:

whether this bounding circle intersects with a Geo with a radius (radians) around it.
