Detailed Description

Random Number Generator Interface.

Author:

Version:

1.0.1

Date:

2005

This is the interface for all random number generator in EOSimulator. They generate two kinds of numbers: integer (NumberGenerator::nextLong) and uniform numbers in [0,1] (NumberGenerator::nextDouble).

NumberGenerators are not directly assigned to a distributions, they are assigned by the use of the label GenType. This enum defines a label for each type of number generator implemented in EOSimulator. Then the label is used by the NumberGeneratorFactory to create an specific number generator for a distribution.

In order to add a new generator in EOSimulator, GenType and NumberGeneratorFactory have to be updated.

Public Member Functions
	NumberGenerator ()
	The constructor of NumberGenerator.
virtual	~NumberGenerator ()
	The destructor of NumberGenerator.
virtual void	setSeed (const unsigned long seed)=0
	This abstract operation assign seed to the generator’s seed.
virtual double	nextDouble ()=0
	This abstract operation returns double between 0 and 1 generated by the generator.
virtual unsigned long	nextLong ()=0
	This abstract operation returns unsigned long generated by the generator.
