Class RngUtils

java.lang.Object

com.numericalmethod.suanshu.stats.random.RngUtils

public class RngUtils
extends java.lang.Object

This class provides static methods that wraps random number generators to produce synchronized generators. For example,

RandomNumberGenerator rng = RngUtils.synchronizedRNG(new Gaussian());

or

RandomLongGenerator rlg = RngUtils.synchronizedRLG(new MersenneTwister());
