Class Organization

Overview

The classes can be grouped into following categories - Primitive base, Intermediate base , disk based  streams and String based streams.

Details

Each of these group  of the classes can be further grouped into two more groups - Input/Output preparation and serialization.

Primitive base classes 

Preparation

These classes serve as base classes for intermediate base classes.

Name	Alias	Parent	Description
ios_base			Base class for the IO stream classes
basic_ios<char,char_traits<char>>	ios	ios_base	Base classes for input and output  stream classes for character type char.
basic_ios<wchar_t,char_traits<wchar_t>>	wios	ios_base	Base classes for input and output  stream classes for character type wchar_t.

Serialization

These base classes support read / write stream operations.

Name	Alias	Parent	Description
basic_streambuf<char,char_traits<char>>	streambuf		Base classes for Serialization/Deserialization of streams for character type char.
basic_streambuf<wchar_t,char_traits<wchar_t>>	wstreambuf		Base classes for Serialization/Deserialization of streams for character type wchar_t.

Intermediate base classes

Preparation

These classes serve as base classes for file and string based streams. 

Name	Alias	Parent	Description
basic_istream<char,char_traits<char>>	istream	ios	Base classes for input stream classes for character type char.
basic_istream<wchar_t,char_traits<wchar_t>>	wistream	wios	Base classes for input stream classes for character type wchar_t.
basic_ostream<char,char_traits<char>>	ostream	ios	Base classes for output stream classes for character type char.
basic_ostream<wchar_t,char_traits<wchar_t>>	wostream	wios	Base classes for output stream classes for character type wchar_t.
basic_iostream<char,char_traits<char>>	iostream	istream, ostream	Base classes for input and output stream classes for character type char.
basic_iostream<wchar_t,char_traits<wchar_t>>	wiostream	wistream, wostream	Base classes for input and output stream classes for character type wchar_t.

Disk based streams

Preparation

These classes support file based stream operation.
