NAME¶

FBB::IRandStream - Istream producing random numbers

SYNOPSIS¶

#include <bobcat/irandstream>
Linking option: -lbobcat

DESCRIPTION¶

FBB::IRandStream objects may be used to extract random numbers in a given range from a stream.

NAMESPACE¶

FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.

INHERITS FROM¶

std::istream,
FBB::RandBuffer (private)

CONSTRUCTORS¶

o

IRandStream(int max):
This FBB::IRandStream() constructor initializes the random generator. The default seed (i.e., 1) for the srand(3) function is used, meaning that every new run of the program will generate the same sequence of random values. Another constructor (see below) is provided when this is not considered appropriate. Random values between 1 and max (inclusive) are returned.

o

IRandStream(int min, int max):
This FBB::IRandStream() constructor initializes the random generator. The default seed (i.e., 1) for the srand(3) function is used, meaning that every new run of the program will generate the same sequence of random values. Another constructor (see below) is provided when this is not considered appropriate. Random values between min and max (inclusive) are returned.

o

IRandStream(int min, int max, size_t seed):
This FBB::IRandStream() constructor initializes the random generator. The seed is used to initialize the random number generator. To start the random generator at some unpredictable point, time(0) could be used. Random values between min and max (inclusive) are returned.

Copy and move constructors (and assignment operators) are not available.

INHERITED MEMBERS¶

Since the class uses public derivation from std::istream, all members of this class can be used.

EXAMPLE¶

#include <iostream>
#include <bobcat/irandstream>
using namespace std;
using namespace FBB;
int main(int argc, char **argv)
{


    IRandStream in(1000);


    for (; argc--; )


    {


        size_t random;


        in >> random;


        cout << random << endl;


    }
}
