Method Detail

intersects

boolean intersects(Shape o)

Returns:

true if edges or areas of this and the specified shapes overlap

intersects

boolean intersects(PointList pointList)

contains

boolean contains(double lat,
                 double lon)

Returns:

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

contains

boolean contains(Shape s)

Returns:

true if the specified shape is fully contained in this shape. Only iff

 s1.contains(s2) && s2.contains(s1) 

then s1 is equal to s2

getBounds

BBox getBounds()

Returns:

the minimal rectangular bounding box of this shape

getCenter

GHPoint getCenter()

Returns:

The center of the shape, if applicable

calculateArea

double calculateArea()

Returns:

an estimated area in m^2
