Copyright David Abrahams, Jeremy Siek, and Thomas Witt 2003. 9 10Each specialization of the ``iterator_adaptor`` class template is derived from 11a specialization of ``iterator_facade``. The core interface functions 12expected by ``iterator_facade`` are implemented in terms of the 13``iterator_adaptor``\ 's ``Base`` template parameter. A class derived 14from ``iterator_adaptor`` typically redefines some of the core 15interface functions to adapt the behavior of the ``Base`` type. 16Whether the derived class models any of the standard iterator concepts 17depends on the operations supported by the ``Base`` type and which 18core interface functions of ``iterator_facade`` are redefined in the 19``Derived`` class. 20
