Inheritance diagram for prf::Ran3nEngine:

Public Member Functions
double	shoot ()
	Generates a random number distributed uniformly between 0 and 1.

void	ResetDefaultState (long seedd)
	Initialize with a given seed.

Public Member Functions inherited from prf::RandomNumberBase
int	createSeed (int inpseed)
	Generate a seed from process id, time ...

double	shoot (double a, double b)
	As above, but between a and b.

double	shoot (double width)
	Between 0 and width.

int	shootBit ()
	Create a random bit, 0 or 1 with equal probabilities.

virtual void	WriteTo (FILE *cnfil)
	Write to a file.

virtual void	ReadFrom (FILE *cnfil)
	Read in the state of the generator from a file.

virtual void	WriteTo_text (FILE *cnfil)
	Write to a file in text form.

virtual void	ReadFrom_text (FILE *cnfil)

virtual void	RandomizeState (int irnk=0)
	Randomize State based on a given "rank".

virtual void	retrace (std::string sttfile="")
	Retrace history.

void	set_seed_and_ncalls (long sd, unsigned long ncl)
	Set seed and num_calls (to later call retrace)

unsigned long	num_calls ()
	Retrieve number of calls.

virtual void	setSeed (long i)
	Sets seed and Initializes with it.

long	Seed () const
	Returns the seed.

virtual void	saveState (std::string sttfile)
	Save complete state for faster recovery.

virtual int	recoverState (std::string sttfile)
	Recover complete state from file.
