org.loudouncodes.randkit.util.Randoms

public final class Randoms
extends Object

RNG utilities for RandKit.

Centralizes the default algorithm choice so distribution classes can depend on a single place for creating generators. This keeps your public API stable even if you later change the underlying algorithm.

Method Details

defaultFactory

public static RandomGeneratorFactory<? extends RandomGenerator> defaultFactory()

Returns a platform-provided, high-quality default generator factory.

Currently uses the LXM family ("L64X128MixRandom") for a good balance of quality and speed on modern JDKs.

Returns:

a RandomGeneratorFactory for the default algorithm

defaultGenerator

public static RandomGenerator defaultGenerator()

Creates a new default generator.

Returns:

a new RandomGenerator instance

seeded

public static RandomGenerator seeded(long seed)

Creates a new default generator seeded for deterministic reproducibility.

Parameters:

seed - seed value

Returns:

a new RandomGenerator instance seeded with seed
