Detailed Description

Creates a discrete distribution for use within SST.

This distribution is the same across platforms and compilers.

Constructor & Destructor Documentation

DiscreteDistribution() [1/2]

SST::RNG::DiscreteDistribution::DiscreteDistribution ( const double *  probs, const uint32_t  probsCount  )

inline

Creates an exponential distribution with a specific lambda.

Parameters

lambda

The lambda of the exponential distribution

References baseDistrib, deleteDistrib, and probabilities.

DiscreteDistribution() [2/2]

SST::RNG::DiscreteDistribution::DiscreteDistribution ( const double *  probs, const uint32_t  probsCount, SST::RNG::Random *  baseDist  )

inline

Creates an exponential distribution with a specific lambda and a base random number generator.

Parameters

lambda	The lambda of the exponential distribution
baseDist	The base random number generator to take the distribution from.

References baseDistrib, deleteDistrib, and probabilities.

Member Function Documentation

getNextDouble()

double SST::RNG::DiscreteDistribution::getNextDouble ( )

inlinevirtual

Gets the next (random) double value in the distribution.

Returns

The next random double from the discrete distribution, this is the double converted of the index where the probability is located

Implements SST::RNG::RandomDistribution.
