org.metacosm.framework.random
Class RandomGenerator  

java.lang.Object
  org.metacosm.framework.random.RandomGenerator

All Implemented Interfaces:

org.metacosm.framework.persistence.Persistent, java.io.Serializable

---

public final class RandomGenerator

extends java.lang.Object

implements org.metacosm.framework.persistence.Persistent

Randomizer for the game
It's a Singleton OOD pattern.

---

Nested Class Summary
(package private)  class	RandomGenerator.FakedRandom           We need to overload the original java.util.Random to be able to get the seed to reproduce a game later.

 

Field Summary
private static RandomGenerator.FakedRandom	random           FakedRandom
private static RandomGenerator	randomGenerator           The instance of the class

 

Constructor Summary
private	RandomGenerator()           The constructor is private because of singleton pattern.

 

Method Summary
int	dice(int nbDice, int nbFaces)           Rolls the given number of dice with the given number of faces.
int	die(int nbFaces)           Rolls a die with the given number of faces.
boolean	getBoolean()
byte	getByte()
double	getDouble()
float	getFloat()
double	getGaussian()
double	getGaussian(double mean, double deviation)
static RandomGenerator	getInstance()
