All Implemented Interfaces:

DiscreteGenerator, Seedable

public class SeedGenerator

extends java.lang.Object

implements DiscreteGenerator

A SeedGenerator is a DiscreteGenerator which produces well-spaced seeds according to its spacing attribute. It relies on a RandomGenerator

Constructor Summary

SeedGenerator()

SeedGenerator(long seed, int spacing)

Method Summary

long	getSeed() Get the random number generator's seed.
void	reseed() Get another seed well-spaced (from the default SeedGenerator)
long	sample()
void	setSeed(long seed) Set the random number generator's seed.
