Constructor Detail

Poisson

public Poisson(double mean)

the seed is aumatically provided by the SeedGenerator

Parameters:

mean - must be greater than 0

Poisson

public Poisson(double mean,
               long seed)

The constructor with which a specific seed is set for the random number generator

Parameters:

seed - The initial seed for the generator, two instances with the same seed will generate the same sequence of numbers

mean - must be greater than 0

Method Detail

sample

public long sample()

Generate a new random number.

Specified by:

sample in interface DiscreteGenerator

Returns:

The next random number in the sequence
