Class LinearRing

java.lang.Object
  com.vividsolutions.jts.geom.Geometry
      com.vividsolutions.jts.geom.LineString
          com.vividsolutions.jts.geom.LinearRing

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable

public class LinearRing
extends LineString

Models an OGC SFS 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.

Constructor Detail

LinearRing

public LinearRing(Coordinate[] points,
                  PrecisionModel precisionModel,
                  int SRID)

Deprecated. Use GeometryFactory instead

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.

precisionModel - the specification of the grid of allowable points for this LinearRing

SRID - the ID of the Spatial Reference System used by this LinearRing

LinearRing

public LinearRing(CoordinateSequence points,
                  GeometryFactory factory)

Constructs a LinearRing with the vertices specifed by the given CoordinateSequence.

Parameters:

points - a sequence points forming a closed and simple linestring, or null to create the empty geometry.
