contains

public boolean contains(double lat1,
                        double lon1)

Specified by:

contains in interface Shape

Returns:

true only if lat and lon are inside (or on the edge) of this shape

getBounds

public BBox getBounds()

Specified by:

getBounds in interface Shape

Returns:

the minimal rectangular bounding box of this shape

getCenter

public GHPoint getCenter()

Specified by:

getCenter in interface Shape

Returns:

The center of the shape, if applicable

intersects

public boolean intersects(Shape o)

Specified by:

intersects in interface Shape
