This is standard C++.  You are apparently already familiar with the
const keyword applied to a function argument (like const _FAR & Object),
which prevents the argument from being modified.  Similarly, if
the const keyword is applied to the member function itself, it means
that the member function may not modify the values of any of the
class object's member variables.  That is, a const member function
has readonly access to other class members.
