Member Function Documentation

checkGenerator()

static void RandomGenerator::checkGenerator ( )

inlinestatic

call this function to check if we need to create new random numbers.

this function is not reentrant! (e.g. call every year in the model)

debugNRandomNumbers()

static int RandomGenerator::debugNRandomNumbers ( )

inlinestatic

debugState()

static void RandomGenerator::debugState ( int &  rIndex, int &  rGeneration, int &  rRefillCount  )

inlinestatic

rand() [1/2]

static double RandomGenerator::rand ( )

inlinestatic

get a random value from [0., 1.]

rand() [2/2]

static double RandomGenerator::rand ( const double  max_value )

inlinestatic

randInt() [1/2]

static unsigned long RandomGenerator::randInt ( )

inlinestatic

get a random integer in [0,2^32-1]

randInt() [2/2]

static unsigned long RandomGenerator::randInt ( const int  max_value )

inlinestatic

randNorm()

double RandomGenerator::randNorm ( const double  mean, const double  stddev  )

inlinestatic

Access to nonuniform random number distributions.

seed()

void RandomGenerator::seed ( const unsigned  oneSeed )

static

set a random generator seed. If oneSeed is 0, then a random number (provided by system time) is used as initial seed.

setGeneratorType()

static void RandomGenerator::setGeneratorType ( const ERandomGenerators  gen )

inlinestatic

set the type of the random generator that should be used.

setup()

static void RandomGenerator::setup ( const ERandomGenerators  gen, const unsigned  oneSeed  )
