Class LinearRing

Hierarchy: Object , Geometry, LineString, LinearRing

All Implemented Interfaces: Cloneable , Comparable , Serializable , Lineal

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.

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

version: 1.7

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

Constructs a LinearRing with the given points.

Parameters:: points - 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 - precisionModel the specification of the grid of allowable points for this LinearRing; SRID - SRID the ID of the Spatial Reference System used by this LinearRing

Throws:: IllegalArgumentException - IllegalArgumentException if the ring is not closed, or has too few points

Deprecation:: Use GeometryFactory instead

public LinearRing(CoordinateSequence points, GeometryFactory factory)

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

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

Throws:: IllegalArgumentException - IllegalArgumentException if the ring is not closed, or has too few points

public int getBoundaryDimension()

Returns Dimension.FALSE, since by definition LinearRings do not have a boundary.

Returns:: Dimension.FALSE

public boolean isClosed()

Tests whether this ring is closed. Empty rings are closed by definition.

Returns:: true if this ring is closed
