Class RandomFactory

java.lang.Object

io.pravega.common.hash.RandomFactory

public class RandomFactory
extends java.lang.Object

Acts as a constructor for java.util.Random objects. This avoids the anti-pattern of int randomInt = new Random().nextInt(); Which is not really random because the default seed is the current time. So this class provides the seed automatically from a master random number generator.
