Class QuadSegment

Implemented Interfaces:
Cloneable
public class QuadSegment
extends Segment
Quadratic Bezier curve segment Note: Most peers don't support quadratics directly, so it might make sense to represent them as cubics internally and just be done with it. I think we should be peer-agnostic, however, and stay faithful to the input geometry types as far as possible.

Field Summary

Point2D

Method Details

clone

public Object clone()
