de.unihalle.informatik.MiToBo.core.datatypes.MTBPolygon2D.IntersectionPoint2D

All Implemented Interfaces:

Serializable, Cloneable

Enclosing class:

MTBPolygon2D

private class MTBPolygon2D.IntersectionPoint2D
extends Point2D.Double

Helper class for function simplify().

This class allows to differentiate between common 2D points in Java and polygon intersection points, while keeping them in a single list.

Constructor Detail

IntersectionPoint2D

public IntersectionPoint2D(double xx,
                           double yy)

Default constructor.

Parameters:

xx - x-coordinate of the point.

yy - y-coordinate of the point.

Method Detail

equals

public boolean equals(Object ptc)

Checks if two intersection points are equal.

According to numerical inaccuracies during intersection calculation, intersection points referring to the same intersection may have small differences in their coordinates. Hence, they are assumed to be equal, if these differences are sufficiently small.

Overrides:

equals in class Point2D
