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;
       }
