All Implemented Interfaces:

Serializable, Cloneable

public class Tausworthe
extends Random

This is a maximally equidistributed combined Tausworthe generator by L'Ecuyer.

The period of this generator is 2^88 (about 10^26). It uses 3 words of state per generator.

Method Detail

getClone

public Tausworthe getClone()

Description copied from class: Random

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface Cloneable

Specified by:

getClone in class Random

Returns:

An exact clone of the current object instance.
