Lets say i need a functor of type
typedef boost::function1
Functor; and i have a function
Ret Foo(Arg1 a, Arg2 b);
Creating a Functor object is easy if i have a Arg2 object
Arg2 arg2;
Functor f(boost::bind<Ret>(&Foo, _1, arg2);
But what if i want to create the Arg2 object in the functor when it is used?
Like i have a function
Arg2 CreateArg2();
and i don't want
Functor f(boost::bind<Ret>(&Foo, _1, CreateArg2());
but something like
Functor f(boost::bind<Ret>(&Foo, _1, &CreateArg2);
so that f(arg1) = Foo(arg1, CreateArg2());
bind( Foo, _1, bind( CreateArg2 ) ).
