Package net.demilich.metastone.game.logic

Class XORShiftRandom

java.lang.Object

java.util.Random

net.demilich.metastone.game.logic.XORShiftRandom

All Implemented Interfaces:

Serializable, Cloneable, RandomGenerator

public class XORShiftRandom
extends Random
implements Serializable, Cloneable

A non-thread-safe random number generator that uses the "XOR Shift" pattern to produce numbers.

This instance is serializable and cloneable. It can be used to reproducibly create sequences of random numbers.
