Detailed Description

template<typename value_type> class arg::bidirectional_iterator

Proxy template class for wrapping bidirectional iterators.

These allow a class interface to be defined without either:

exposing the choice of container used in the implementation,
imposing a choice of container on the client code, or
templating member functions on the type of iterators.

Note that MSVC5 has some serious problems compiling and using this class (see number of _MSC_VER == 1100 frigs in the test harness).

All methods support the strong exception safety guarantee with the proviso that the wrapped iterator must have a non-throwing destructor.
