Class SegmentPointComparator

java.lang.Object
org.locationtech.jts.noding.SegmentPointComparator

public class SegmentPointComparator extends Object
Implements a robust method of comparing the relative position of two points along the same segment. The coordinates are assumed to lie "near" the segment. This means that this algorithm will only return correct results if the input coordinates have the same precision and correspond to rounded values of exact coordinates lying on the segment.

      public static int compare(int octant, Coordinate p0, Coordinate p1)
      Compares two Coordinates for their relative position along a segment lying in the specified Octant.
      Returns:
      -1 node0 occurs first; 0 the two nodes are equal; 1 node1 occurs first
