FBB::RandBuffer(3bobcat)				      random number streambuf					  FBB::RandBuffer(3bobcat)

NAME
FBB::RandBuffer - std::streambuf generating random numbers
SYNOPSIS
#include <bobcat/randbuffer> 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 Randbuffer(int min, int max, size_t seed = 1): This Randbuffer() constructor initializes the random generator. The seed is used to initialze the random number generator.Random values between min and max (inclusive) are returned.
VIRTUAL MEMBERS
o int underflow(): This function is called by std::istream objects using Randbuffer. It produces the next available random number, separating the ran- dom numbers by one blanks space. Random values between min and max (inclusive) are returned (see the description of the construc- tor).
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 <bobcat/randbuffer> #include <bobcat/a2x> using namespace std; using namespace FBB; int main(int argc, char **argv) { if (argc == 1) { cout << "expect: nruns min max seed "; return 1; } Randbuffer rb(A2x(argv[2]), A2x(argv[3]), A2x(argv[4]).to<size_t>()); istream istr(&rb); for (int idx = A2x(argv[1]); idx--; ) { int c; if (!(istr >> c)) { cout << "extraction failed "; 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; return 0; }
