Class BakerTransformedPointSet

java.lang.Object

umontreal.iro.lecuyer.hups.PointSet

umontreal.iro.lecuyer.hups.ContainerPointSet

umontreal.iro.lecuyer.hups.BakerTransformedPointSet

public class BakerTransformedPointSet
extends ContainerPointSet

This container class embodies a point set to which a Baker transformation is applied. It transforms each coordinate u into 2u if u <= 1/2 and 2(1 - u) if u > 1/2.

Constructor Detail

BakerTransformedPointSet

public BakerTransformedPointSet(PointSet P)

Constructs a Baker-transformed point set from the given point set P.

Parameters:

P - point set for which we want a Baker-transfomed version

Method Detail

getCoordinate

public double getCoordinate(int i,
                   int j)

Description copied from class: PointSet

Returns u_{i, j}, the coordinate j of the point i.

Overrides:

getCoordinate in class ContainerPointSet

Parameters:

i - index of the point to look for

j - index of the coordinate to look for

Returns:

the value of u_{i, j}

iterator

public PointSetIterator iterator()

Description copied from class: PointSet

Constructs and returns a point set iterator. The default implementation returns an iterator that uses the method getCoordinate (i,j) to iterate over the points and coordinates, but subclasses can reimplement it for better efficiency.

Overrides:

iterator in class ContainerPointSet

Returns:

point set iterator for the point set

toString

public java.lang.String toString()

Description copied from class: PointSet

Formats a string that contains information about the point set.

Overrides:

toString in class ContainerPointSet

Returns:

string representation of the point set information
