Package org.apache.commons.rng.sampling.distribution

Class DiscreteUniformSampler

java.lang.Object
org.apache.commons.rng.sampling.distribution.SamplerBase
org.apache.commons.rng.sampling.distribution.DiscreteUniformSampler
All Implemented Interfaces:
DiscreteSampler
public class DiscreteUniformSampler
extends SamplerBase
implements DiscreteSampler
Discrete uniform distribution sampler.

Sampling uses UniformRandomProvider.nextInt(int) when the range (upper - lower) < Integer.MAX_VALUE, otherwise UniformRandomProvider.nextInt().

Since:
