I see. So sub-classing basic_string<char> would be the reccomended way =
to do
this then?

With respect to the over-ridden methods I am wondering whether you have =
some
example code that I can see. I know how to call base class methods from =
a
derived class but what I need is a way to reverse the default method =
called
(usually the derived method is called, I want the base to be called, if =
one
exist)=20

The concept is a bit stupid... You can check what members the =
std::string
has. anyway  in general if you inherit from a class and you do not know =
what
member functions has(?!) if a member function exists, is non-virtual by =
its
creator and takes the same arguments as yours, you can use that function =
by
using a base pointer. For example:
=20
=20
class whatever
{
 // ...
=20
 public:
 // ...
=20
 int something() const;
};
=20
=20
class your_class: public whatever
{
 // ...
=20
 public:
 //...
=20
 // You happen to define something() and
 // you did not know it existed(!?)
 void something() const;
};
=20
=20
whatever *p=3Dnew your_class;
=20
=20
//whatever::something() is called
// and not your definition
p->something();
