Member Function Documentation

template<typename T> virtual bool more::io::buffer< T >::driver::is_error (    )  [inline, virtual]

Shall return true on error.

template<typename T> virtual T* more::io::buffer< T >::driver::read (  T *    first, T *    last )  [inline, virtual]

Overload to provide input. If overloaded this function shall shall fill a range [first, stop), where first <= stop < last, with items and return stop. Return 0 to indicate end of input. The default is to return last, which gives a infinite sequence of junk (default constructed, or previously assigned) elements, which is suitable for a pure output stream.

template<typename T> virtual void more::io::buffer< T >::driver::write (  T *    first, T *    last )  [inline, virtual]

Overload to receive output. If overloaded write [first, last) to the tied output channel. The default is to do nothing, which is suitable for a pure input stream.
