    21 //  function class

    22 //

    23 //      Lazy functions

    24 //

    25 //      This class provides a mechanism for lazily evaluating functions.

    26 //      Syntactically, a lazy function looks like an ordinary C/C++

    27 //      function. The function call looks the same. However, unlike

    28 //      ordinary functions, the actual function execution is deferred.

    29 //      (see actor.hpp, primitives.hpp and composite.hpp for an

    30 //      overview). For example here are sample factorial function calls:

    31 //

    32 //          factorial(4)

    33 //          factorial(arg1)

    34 //          factorial(arg1 * 6)

    35 //

    36 //      These functions are automatically lazily bound unlike ordinary

    37 //      function pointers or functor objects that need to be explicitly

    38 //      bound through the bind function (see binders.hpp).

    39 //

    40 //      A lazy function works in conjunction with a user defined functor

    41 //      (as usual with a member operator()). Only special forms of

    42 //      functor objects are allowed. This is required to enable true

    43 //      polymorphism (STL style monomorphic functors and function

    44 //      pointers can still be used through the bind facility in

    45 //      binders.hpp).

    46 //

    47 //      This special functor is expected to have a nested template class

    48 //      result<A...TN> (where N is the number of arguments of its

    49 //      member operator()). The nested template class result should have

    50 //      a typedef 'type' that reflects the return type of its member

    51 //      operator(). This is essentially a type computer that answers the

    52 //      metaprogramming question "Given arguments of type A...TN, what

    53 //      will be the operator()'s return type?".

    54 //

    55 //      There is a special case for functors that accept no arguments.

    56 //      Such nullary functors are only required to define a typedef

    57 //      result_type that reflects the return type of its operator().

    58 //

    59 //      Here's an example of a simple functor that computes the

    60 //      factorial of a number:

    61 //

    62 //          struct factorial_impl {

    63 //

    64 //              template <typename Arg>

    65 //              struct result { typedef Arg type; };

    66 //

    67 //              template <typename Arg>

    68 //              Arg operator()(Arg n) const

    69 //              { return (n <= 0) ? 1 : n * this->operator()(n-1); }

    70 //          };

    71 //

    72 //      As can be seen, the functor can be polymorphic. Its arguments

    73 //      and return type are not fixed to a particular type. The example

    74 //      above for example, can handle any type as long as it can carry

    75 //      out the required operations (i.e. <=, * and -).

    76 //

    77 //      We can now declare and instantiate a lazy 'factorial' function:

    78 //

    79 //          function<factorial_impl> factorial;

    80 //

    81 //      Invoking a lazy function 'factorial' does not immediately

    82 //      execute the functor factorial_impl. Instead, a composite (see

    83 //      composite.hpp) object is created and returned to the caller.

    84 //      Example:

    85 //

    86 //          factorial(arg1)

    87 //

    88 //      does nothing more than return a composite. A second function

    89 //      call will invoke the actual factorial function. Example:

    90 //

    91 //          int i = 4;

    92 //          cout << factorial(arg1)(i);

    93 //

    94 //      will print out "24".

    95 //

    96 //      Take note that in certain cases (e.g. for functors with state),

    97 //      an instance may be passed on to the constructor. Example:

    98 //

    99 //          function<factorial_impl> factorial(ftor);

   100 //

   101 //      where ftor is an instance of factorial_impl (this is not

   102 //      necessary in this case since factorial is a simple stateless

   103 //      functor). Take care though when using functors with state

   104 //      because the functors are taken in by value. It is best to keep

   105 //      the data manipulated by a functor outside the functor itself and

   106 //      keep a reference to this data inside the functor. Also, it is

   107 //      best to keep functors as small as possible.
