public class LinearRing extends LineString
LinearRing
.
A LinearRing is a LineString which is both closed and simple.
In other words,
the first and last coordinate in the ring must be equal,
and the interior of the ring must not self-intersect.
Either orientation of the ring is allowed.
A ring must have either 0 or 4 or more points.
The first and last points must be equal (in 2D).
If these conditions are not met, the constructors throw
an IllegalArgumentException

Constructs a
LinearRing with the vertices
specifed by the given CoordinateSequence . |
Modifier and Type | Method and Description |
---|---|
int |
getBoundaryDimension()
Returns
Dimension.FALSE , since by definition LinearRings do
not have a boundary. |
java.lang.String |
getGeometryType()
Returns the name of this object's
com.vivid.jts.geom
interface. |
boolean |
isSimple()
Returns
true , since by definition LinearRings are always simple. |
