Method Detail

setModel

public void setModel(Line2D param)

Description copied from interface: DistanceFromModel

Sets the model parameters.

Specified by:

setModel in interface DistanceFromModel<Line2D,Point2D>

Parameters:

param - Model parameters.

computeDistance

public double computeDistance(Point2D p)

Description copied from interface: DistanceFromModel

Computes the distance the point is from the model.

Specified by:

computeDistance in interface DistanceFromModel<Line2D,Point2D>

p - Point being evaluated. Not modified.

Returns:

Distance the point is from the model.

computeDistance

public void computeDistance(java.util.List<Point2D> obs,
                            double[] distance)

There are some situations where processing everything as a list can speed things up a lot. This is not one of them.

Specified by:

computeDistance in interface DistanceFromModel<Line2D,Point2D>

Parameters:

obs - Set of points which are to be evaluated.

distance - Where model distance is stored.
