Class LineSegment

java.lang.Object
  geometry.LineSegment

public final class LineSegment
extends Object

This class represents the choice of a line segment in the complex plane. This class is immutable. That is, once a LineSegment is constructed, it will not change.

Constructor Summary

LineSegment(Complex starting_point, Complex ending_point)
Construct a new LineSegment from a start and an end.

LineSegment(LineSegment seg, Similarity sim)
Construct the image of a line segment under a similarity

Method Summary

Complex	endingPoint() Return the endpoint.
double	length() Return the distance between the starting and ending points.
Complex	midpoint() Return the point midway between the starting and ending points.
Complex	startingPoint() Return the starting point.
