Detailed Description

Creates a discrete distribution for use within SST.

This distribution is the same across platforms and compilers.

Constructor & Destructor Documentation

DiscreteDistribution() [1/3]

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

inline

Creates a discrete probability distribution.

Parameters

probs	An array of probabilities for each outcome
probsCount	The number of discrete outcomes

DiscreteDistribution() [2/3]

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.

DiscreteDistribution() [3/3]

SST::RNG::DiscreteDistribution::DiscreteDistribution ( )

inline

Default constructor.

FOR SERIALIZATION ONLY.

Member Function Documentation

getNextDouble()

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

inlineoverridevirtual

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.

Field Documentation

deleteDistrib

ImplementSerializable (SST::RNG::DiscreteDistribution) protected bool SST::RNG::DiscreteDistribution::deleteDistrib

Serialization macro.

Sets the base random number generator for the distribution. Controls whether the base distribution should be deleted when this class is destructed.
