Detailed Description

Define and collect ways to generate random values and values from random distributions.

Of particular use when encountering MathML defined by the 'Distributions' SBML L3 package.

Constructor & Destructor Documentation

Random()

rrllvm::Random::Random

(

)

default ctor, this obviously does not add any mappings to a ModelGeneratorContext.

This would be used when a Random is created by itself, to use the attached RNG engine.

Member Function Documentation

getRandomSeed()

int64_t rrllvm::Random::getRandomSeed

(

)

Try to hide the RNG so we can used different RNGs in the future.

get the seed used by the RNG.

max()

double rrllvm::Random::max ( )

inline

max random number.

MSVC looks at this, but gcc stdlib assumes normalized dist.

min()

double rrllvm::Random::min ( )

inline

min random number.

MSVC looks at this, but gcc stdlib assumes normalized dist.

setRandomSeed()

void rrllvm::Random::setRandomSeed

(

int64_t

val

)

Try to hide the RNG, so we can use different RNGs in the future.

set the seed used by the random number generator. This will by definition reset the RNG.
