Interface LinearRing

All Superinterfaces:

Cloneable, Comparable<Object>, DataTypeProxy, Geometry, Lineal, LineString, Serializable

All Known Implementing Classes:

LinearRingDoubleGf

public interface 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
