public class UniformDiscreteDistribution
extends DiscreteDistribution

Class to represent a distribution made of a finite number of mass points of which each is as likely to be drawn than any other. Although functionally equivalent to a FiniteMassPointDistribution, the values with be drawn in constant time, since no information about the mass of the points is needed.
