Detailed Description

Random generator for discrete uniform distributed variates.

This class creates a set of discrete values, uniformly distributed in the range [0.0, 1.0). The random values are then drawn from this set of discrete values, with all values equal probability (i.e. the PDF of the index distribution is also uniform).

Constructor & Destructor Documentation

simth::DiscreteUniformRng::DiscreteUniformRng (  size_t  K  )

Constructor for a discrete distribution with K distinct values in the set of possible values.

virtual simth::DiscreteUniformRng::~DiscreteUniformRng (   )  [virtual]

Member Function Documentation

virtual double simth::DiscreteUniformRng::get (   )  const [virtual]

Returns a random variate with the described uniform distribution in the range of [0,1). Implements simth::RandomGenerator.

double simth::DiscreteUniformRng::get_inl (   )  const [inline]

Non-virtual inline version of get().

void simth::DiscreteUniformRng::refresh (  size_t  K = 0  )

Refreshs the set of discrete values, i.e. dices a new set of them. Parameters: K  The number of discrete values, i.e. the size of the set. If zero, leaves the size of the set unchanged.
