NAME

       FBB::RandBuffer - std::streambuf generating random numbers

SYNOPSIS

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

DESCRIPTION

       FBB:RandBuffer objects may be used as a std::streambuf of std::istream objects to allow the extraction of
       random numbers from the stream.

NAMESPACE

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

INHERITS FROM

       std::streambuf

CONSTRUCTOR

       o      RandBuf(int min, int max, size_t seed = 1):
              This RandBuf() constructor initializes the random generator. The seed is used  to  initialize  the
              random number generator.Random values between min and max (inclusive) are returned.

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

VIRTUAL MEMBERS

       o      int underflow():
              This  function  is  called  by  std::istream objects using RandBuf. It produces the next available
              random number, separating the random numbers by one blanks space. Random values  between  min  and
              max (inclusive) are returned (see the description of the constructor).

INHERITED MEMBERS

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

EXAMPLE

       #include <iostream>
       #include <istream>

       #include "../randbuf"

       using namespace std;
       using namespace FBB;

       int main(int argc, char **argv)
       {
           if (argc == 1)
           {
               cout << "expect: nruns min max seed\n";
               return 1;
           }

           RandBuf rb(stoi(argv[2]), stoi(argv[3]), stoul(argv[4]));

           istream istr(&rb);

           for (unsigned idx = stoul(argv[1]); idx--; )
           {
               int c;
               if (!(istr >> c))
               {
                   cout << "extraction failed\n";
                   break;
               }
               cout << "next: " << c << endl;
           }

           int count = 0;
           while (istr.unget())
               count++;

           cout << "number of successful unget()-calls: " << count << endl;
           istr.clear();
           istr >> count;
           cout << "and read: " << count << endl;
       }
