Method Details

computeIntersect

protected int computeIntersect(Coordinate p1,
                               Coordinate p2,
                               Coordinate p3,
                               Coordinate p4)
Overrides:
computeIntersect in interface LineIntersector

computeIntersection

public void computeIntersection(Coordinate p,
                                Coordinate p1,
                                Coordinate p2)
Overrides:
computeIntersection in interface LineIntersector

isSameSignAndNonZero

public static boolean isSameSignAndNonZero(double a,
                                           double b)
Returns:
true if both numbers are positive or if both numbers are negative. Returns false if both numbers are zero.
