Class CurveSegmentImpl

java.lang.Object
  org.deegree.model.spatialschema.CurveSegmentImpl

All Implemented Interfaces:

Serializable, CurveSegment, GenericCurve

Direct Known Subclasses:

LineStringImpl

abstract class CurveSegmentImpl
extends Object
implements CurveSegment, Serializable

default implementation of the CurveSegment interface from package jago.model. the class is abstract because it should be specialized by derived classes LineString for example

CurveSegmentImpl(Position[] gmps, CoordinateSystem crs) Creates a new CurveSegmentImpl object.

Method Summary

boolean	contains(Geometry gmo) The Boolean valued operation "contains" shall return TRUE if this Geometry contains another Geometry.
boolean	equals(Object other) checks if this curve segment is completly equal to the submitted geometry
CoordinateSystem	getCoordinateSystem() returns the coordinate system of the curve segment
Point	getEndPoint() returns the last point of the curve. if the curve segment doesn't contain a point null will be returned
int	getNumberOfPoints() returns the number of points building the curve or curve segment
Position	getPositionAt(int index) returns the curve segment position at the submitted index
Position[]	getPositions() returns all positions of the segement as array of Position.
Point	getStartPoint() returns the first point of the curve. if the curve segment doesn't contain a point null will be returned
void	reverse() reverses the direction of the curvesegment
