Detailed Description

Basic implementation of LinearRing.

The first and last point in the coordinate sequence must be equal. Either orientation of the ring is allowed. A valid ring must not self-intersect.


Constructor & Destructor Documentation

geos::geom::LinearRing::LinearRing ( CoordinateSequence points,
const GeometryFactory newFactory 
)

Constructs a LinearRing with the given points.

Parameters:
points points forming a closed and simple linestring, or null or an empty array to create the empty geometry. This array must not contain null elements. If not null LinearRing will take ownership of points.
newFactory the GeometryFactory used to create this geometry
