The latest version of this topic can be found at <sstream>.

Defines several template classes that support iostreams operations on sequences stored in an allocated array object. Such sequences are easily converted to and from objects of template class basic_string.

Syntax

namespace std {
template <class CharType, class Traits = char_traits<CharType>, class Allocator = allocator<CharType>>
class basic_stringbuf;
typedef basic_stringbuf<char>  
stringbuf;
typedef basic_stringbuf<wchar_t> wstringbuf;

template <class CharType, class Traits = char_traits<CharType>, class Allocator = allocator<CharType>>
class basic_istringstream;
typedef basic_istringstream<char>  
istringstream;
typedef basic_istringstream<wchar_t> wistringstream;

template <class CharType, class Traits = char_traits<CharType>, class Allocator = allocator<CharType>>
class basic_ostringstream;
typedef basic_ostringstream<char>  
ostringstream;
typedef basic_ostringstream<wchar_t> wostringstream;

template <class CharType, class Traits = char_traits<CharType>, class Allocator = allocator<CharType>>
class basic_stringstream;
typedef basic_stringstream<char>  
stringstream;
typedef basic_stringstream<wchar_t> wstringstream;
// TEMPLATE FUNCTIONS
template <class CharType, class Traits, class Allocator>
void swap(
    basic_stringbuf<CharType, Traits, Allocator>& left,
    basic_stringbuf<CharType, Traits, Allocator>& right);

template <class CharType, class Traits, class Allocator>
void swap(
    basic_istringstream<CharType, Traits, Allocator>& left,
    basic_istringstream<CharType, Traits, Allocator>& right);

template <class CharType, class Traits, class Allocator>
void swap(
    basic_ostringstream<CharType, Traits, Allocator>& left,
    basic_ostringstream<CharType, Traits, Allocator>& right);

template <class CharType, class Traits, class Allocator>
void swap (
    basic_stringstream<CharType, Traits, Allocator>& left,
    basic_stringstream<CharType, Traits, Allocator>& right);

}  // namespace std

Parameters

Parameter	Description
`left`	Reference to an `sstream` object.
`right`	Reference to an `sstream` object.

Remarks

Objects of type char * can use the functionality in <strstream> for streaming. However, <strstream> is deprecated and the use of <sstream> is encouraged.

Typedefs

istringstream	Creates a type `basic_istringstream` specialized on a `char` template parameter.
ostringstream	Creates a type `basic_ostringstream` specialized on a `char` template parameter.
stringbuf	Creates a type `basic_stringbuf` specialized on a `char` template parameter.
stringstream	Creates a type `basic_stringstream` specialized on a `char` template parameter.
wistringstream	Creates a type `basic_istringstream` specialized on a `wchar_t` template parameter.
wostringstream	Creates a type `basic_ostringstream` specialized on a `wchar_t` template parameter.
wstringbuf	Creates a type `basic_stringbuf` specialized on a `wchar_t` template parameter.
wstringstream	Creates a type `basic_stringstream` specialized on a `wchar_t` template parameter.

Manipulators

swap	Exchanges the values between two `sstream` objects.

Classes

basic_stringbuf	Describes a stream buffer that controls the transmission of elements of type Elem, whose character traits are determined by the class Tr, to and from a sequence of elements stored in an array object.
basic_istringstream	Describes an object that controls extraction of elements and encoded objects from a stream buffer of class basic_stringbuf<Elem, Tr, `Alloc`>, with elements of type Elem, whose character traits are determined by the class Tr, and whose elements are allocated by an allocator of class `Alloc`.
basic_ostringstream	Describes an object that controls insertion of elements and encoded objects into a stream buffer of class basic_stringbuf<Elem, Tr, `Alloc`>, with elements of type Elem, whose character traits are determined by the class Tr, and whose elements are allocated by an allocator of class `Alloc`.
basic_stringstream	Describes an object that controls insertion and extraction of elements and encoded objects using a stream buffer of class basic_stringbuf<Elem, Tr, `Alloc`>, with elements of type Elem, whose character traits are determined by the class Tr, and whose elements are allocated by an allocator of class `Alloc`.
