Interface GM_Curve

All Superinterfaces:

GM_GenericCurve, GM_Object, GM_OrientableCurve, GM_OrientablePrimitive, GM_Primitive

All Known Implementing Classes:

GM_Curve_Impl

public interface GM_Curve

extends GM_OrientableCurve, GM_GenericCurve

The interface defines the access to curve geometries. Curves are made of one or more curve segments.

Method Summary

void	addCurveSegment(GM_CurveSegment segment) adds a segment at the end of the curve
void	deleteCurveSegmentAt(int index) deletes the segment at the submitted index
GM_CurveSegment	getCurveSegmentAt(int index) returns the curve segment at the submitted index
int	getNumberOfCurveSegments() returns the number of segments building the curve
void	insertCurveSegmentAt(GM_CurveSegment segment, int index) inserts a segment in the curve at the submitted position. all points with a position that equals index or is higher will be shifted
void	setCurveSegmentAt(GM_CurveSegment segment, int index) writes a segment to the curve at submitted position. the old point will be deleted
