Class RandomStart

java.lang.Object
  umontreal.iro.lecuyer.hups.RandomStart

All Implemented Interfaces:

PointSetRandomization

public class RandomStart
extends Object
implements PointSetRandomization

This class implements a PointSetRandomization that randomizes a sequence with a random starting point. The point set must be an instance of HaltonSequence or an IllegalArgumentException is thrown. For now, only the Halton sequence is allowed, but there may be others later.

Constructor Summary

RandomStart()
Empty constructor.

RandomStart(RandomStream stream)
Sets internal variable stream to the given stream.

Method Summary

RandomStream	getStream() Returns the internal RandomStream.
void	randomize(PointSet p) This method calls init.
void	setStream(RandomStream stream) Sets the internal RandomStream to stream.

RandomStart

public RandomStart(RandomStream stream)

Sets internal variable stream to the given stream.

Parameters:

stream - stream to use in the randomization

Method Detail

randomize

public void randomize(PointSet p)

p - Point set to randomize

setStream

public void setStream(RandomStream stream)

Sets the internal RandomStream to stream.

Specified by:

setStream in interface PointSetRandomization

Parameters:

stream - stream to use in the randomization

getStream

public RandomStream getStream()

Returns the internal RandomStream.

Specified by:

getStream in interface PointSetRandomization

Returns:

stream used in the randomization
