RWvios

Synopsis

#include <vstream.h>

(abstract base class)

Description

RWvios is an abstract base class. It defines an interface similar to the C++ streams class ios. However, unlike ios, it offers the advantage of not necessarily being associated with a streambuf.

This is useful for classes that cannot use a streambuf in their implementation. An example of such a class is RWXDRistream, where the XDR model does not permit streambuf functionality.

Specializing classes that do use streambufs in their implementation (e.g., RWpistream) can usually just return the corresponding ios function.
