And that object pointer passing was missing in my code and
was achieved in your code through the binding? I had already
looked at boost::bind but still cannot figure out its interface
template unspecified-3-1 bind(F f, A1 a1);
What is this returning?
Following the boost::bind reference is not an easy task. :-) First, you need
template unspecified-5 bind(R (T::*f) (), A1 a1)
Effects: equivalent to bind<R>(boost::mem_fn(f), a1);
since the first argument is a member function. This redirects you to
template unspecified-3 bind(F f, A1 a1)
Returns: a function object λ such that the expression λ(v1, v2, ..., vm) is
equivalent to f(µ(a1, v1, v2, ..., vm)), implicitly converted to R.
Throws: Nothing unless the copy constructors of F or A1 throw an exception.
and all this translated to English means that
boost::bind(&Manager::Check, this)
returns a function object that, when called, returns
boost::mem_fn(&Manager::Check)(this)
that, in turn (see the mem_fn documentation) is equivalent to
(this->*&Manager::Check)();
The thing to remember is that member functions have an additional implicit
argument, the object pointer/reference.
