Class Octant

java.lang.Object

org.locationtech.jts.noding.Octant

public class Octant
extends Object

Methods for computing and working with octants of the Cartesian plane Octants are numbered as follows:

  \2|1/
 3 \|/ 0
 ---+--
 4 /|\ 7
  /5|6\
 

If line segments lie along a coordinate axis, the octant is the lower of the two possible values.

Method Summary

Modifier and Type	Method and Description
static int	octant(Coordinate p0, Coordinate p1) Returns the octant of a directed line segment from p0 to p1.
static int	octant(double dx, double dy) Returns the octant of a directed line segment (specified as x and y displacements, which cannot both be 0).
