Method Detail

minimumDistance

public double minimumDistance(Point2D p,
                              double tolerance)

Returns the minimum distance from the specified point to an infinite straight-line. Note that unlike a Ray3D, the points that define the infinite line are not taken account, just the line direction.

Overrides:

minimumDistance in class Curve2D

Parameters:

p - Point to find minimum distance to this line.

tolerance - Required tolerance.

Returns:

Minimum distance between this line and the specified point.

toString

public java.lang.String toString()

Returns a String representation of an InfiniteStraightLine2D object.

Overrides:

toString in class LinearLine2D

Returns:

A String representation of an InfiniteStraightLine2D object.
