Class SeCurve

java.lang.Object
  com.esri.sde.sdk.geom.SeGeometry
      com.esri.sde.sdk.geom.SeCurve

All Implemented Interfaces:

Curve, Geometry, java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

SeLinestring

public abstract class SeCurve
extends SeGeometry
implements Curve

This class represents a one-dimensional geometric object usually stored as a sequence of points, its subtype specifies the form of the interpolation between points. One subclass of SeCurve is SeLinestring, which uses linear interpolation between points.

Method Summary

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