Constructor & Destructor Documentation

BasicRandom()

fastjet::BasicRandom< double >::BasicRandom ( int  __s1 = 12345, int  __s2 = 67890  )

inlineexplicit

constructor that takes two integers to specify the seed

Definition at line 170 of file BasicRandom.hh.

Member Function Documentation

operator()() [1/3]

value_type fastjet::BasicRandom< double >::operator() ( )

inline

return a single pseudorandom double number, in the range 0.0 to 1.0 (not sure whether this range is open or closed)

Definition at line 177 of file BasicRandom.hh.

operator()() [2/3]

void fastjet::BasicRandom< double >::operator() ( size_type  __n, pointer  __res  )

inline

given a pointer __res to the beginning of an array, fill that array with __n random numbers

Definition at line 183 of file BasicRandom.hh.

operator()() [3/3]

void fastjet::BasicRandom< double >::operator() ( size_type  __n, pointer  __res, std::vector< int > &  __iseed  )

inline

given a pointer __res to the beginning of an array, fill that array with __n random numbers

This now acquired an extra argument which allows to retreive the set of seeds used for this generation.

Definition at line 193 of file BasicRandom.hh.

randomize()

void fastjet::BasicRandom< double >::randomize ( void *  __iseed )

inline

(re)initialize the random number generator from an array of seeds

Definition at line 208 of file BasicRandom.hh.

set_status()

void fastjet::BasicRandom< double >::set_status ( const std::vector< int > &  __iseed )

inline

Definition at line 214 of file BasicRandom.hh.

get_status()

void fastjet::BasicRandom< double >::get_status ( std::vector< int > &  __iseed )

inline

Definition at line 220 of file BasicRandom.hh.

min()

static value_type fastjet::BasicRandom< double >::min ( )

inlinestatic

minimum value returned by the generator

Definition at line 227 of file BasicRandom.hh.

max()

static value_type fastjet::BasicRandom< double >::max ( )

inlinestatic

maximum value returned by the generator

Definition at line 229 of file BasicRandom.hh.

print_info()

void fastjet::BasicRandom< double >::print_info ( std::ostream &  __os = std::cout )
