Class SeedFactory

org.apache.commons.rng.simple.internal.SeedFactory

public final class SeedFactory
extends java.lang.Object

Utilities related to seeding.

This class provides methods to generate random seeds (single values or arrays of values, of int or long types) that can be passed to the methods that create a generator instance.
Although the seed-generating methods defined in this class will likely return different values for all calls, there is no guarantee that the produced seed will result always in a "good" sequence of numbers (even if the generator initialized with that seed is good).
There is no guarantee that sequences will not overlap.
