Interface Curve

All Superinterfaces:

Geometry

All Known Subinterfaces:

Linestring

All Known Implementing Classes:

SeCurve, SeLinestring

public interface Curve
extends Geometry

The Curve interface defines the methods for a class whose instances create a one-dimensional geometric object stored as a sequence of points.

Method Summary

Point	endPoint() Returns the last point of a linestring.
boolean	isClosed() Isclosed takes a linestring or multilinestring and returns t (TRUE) if it is closed; otherwise it returns f (FALSE).
boolean	isRing() Isring takes a linestring and returns t (TRUE) if it is a ring (i.e., the linestring is closed and simple); otherwise it returns f (FALSE).
double	length() Returns the length of a linestring or multilinestring.
Point	startPoint() Returns the first point of a linestring.

isRing

boolean isRing()
               throws GeometryException

Isring takes a linestring and returns t (TRUE) if it is a ring (i.e., the linestring is closed and simple); otherwise it returns f (FALSE).
