NAME

       FBB::repeat - call a (member) function a fixed number of times

SYNOPSIS

       #include <bobcat/repeat>

DESCRIPTION

       The  FBB::repeat  function  template  allows  a function or member function to be called a
       certain number of times. The functions or member functions may define arguments. Arguments
       to these functions are specified when repeat is called, and are perfectly forwarded by the
       repeat function template to the (member) function called by repeat.

       The first argument of the repeat  function  template  defines  the  number  of  times  the
       (member) function must be called.

       The  FBB::repeat  function template are defined inline, allowing the compiler to `optimize
       away’ the repeat function call itself.

NAMESPACE

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

REPEAT FUNCTION TEMPLATE

       The repeat function template is declared as:

       template <typename Counter, typename First, typename ...Params>
       void repeat(Counter counter, First &&first, Params &&...params);

       In this declaration,

       o      Counter  represents  the  counter’s  type.  Usually  an int or size_t. When calling
              repeat counter must be initialized to the number of  times  repeat  must  call  the
              (member) function (see below);

       o      First  represents  the  prototype  of a function or the name of a class.  name of a
              class. Likewise, first either is the address (name) of the function to be called or
              the name of an object of class type First. In the latter case the object may or may
              not be a const object.

       o      ...Params represents the  set  of  parameter  types  of  arguments  which  must  be
              perfectly  forwarded  to  the  called  function.  If  first represents a class type
              object, the first argument must be the address of a member function  of  the  class
              First.

EXAMPLES

       #include <iostream>
       #include <iterator>
       #include <algorithm>

       #include "../repeat"

       using namespace std;
       using namespace FBB;

       class Object
       {
           public:
               void member(int argc, char **argv) const;
               void member2(size_t &rept, int argc, char **argv);
       };

       void Object::member(int argc, char **argv) const
       {
           cout << "member called\n";
           copy(argv, argv + argc, ostream_iterator<char const *>(cout, "\n"));
       }

       void Object::member2(size_t &rept, int argc, char **argv)
       {
           cout << "member2 called, iteration " << rept++ << "\n";
           copy(argv, argv + argc, ostream_iterator<char const *>(cout, "\n"));
       }

       void fun()
       {
           cout << "Fun called\n";
       }

       int main(int argc, char **argv)
       {
           Object object;

           cout << "\n"
                   "*** The number of arguments determines the repeat-count ***\n\n";

           cout << "Fun without arguments:\n";
           repeat(argc, fun);

           cout << "Object receiving argc and argv:\n";
           repeat(argc, object, &Object::member, argc, argv);

           cout << "Object receiving argc and argv, showing the iteration count:\n";
           size_t count = 0;
           repeat(argc, object, &Object::member2, count, argc, argv);

           Object const obj;
           cout << "Const Object receiving argc and argv:\n";
           repeat(argc, obj, &Object::member, argc, argv);

       }

BUGS

       Be  careful when using overloaded functions, as the template argument resolution mechanism
       may be unable to determine which function to call. If overloaded functions must be used, a
       static_cast is likely required to disambiguate your intentions.
