Detailed Description

   template<typename _CharT, typename _Traits, typename _Alloc>
       class std::basic_stringstream< _CharT, _Traits, _Alloc >" Controlling input and output for
       std::string.

       Template Parameters
           _CharT Type of character stream.
           _Traits Traits for character type, defaults to char_traits<_CharT>.
           _Alloc Allocator type, defaults to allocator<_CharT>.

       This class supports reading from and writing to objects of type std::basic_string, using
       the inherited functions from std::basic_iostream. To control the associated sequence, an
       instance of std::basic_stringbuf is used, which this page refers to as sb.

Constructor & Destructor Documentation

   template<typename _CharT , typename _Traits , typename _Alloc > std::basic_stringstream<
       _CharT, _Traits, _Alloc >::basic_stringstream () [inline]
       Default constructor starts with an empty string buffer. Initializes sb using the mode
       in|out, and passes &sb to the base class initializer. Does not allocate any buffer.

       That's a lie. We initialize the base class with NULL, because the string class does its
       own memory management.

       Definition at line 741 of file sstream.

   template<typename _CharT , typename _Traits , typename _Alloc > std::basic_stringstream<
       _CharT, _Traits, _Alloc >::basic_stringstream (ios_base::openmode __m) [inline],
       [explicit]
       Starts with an empty string buffer.

       Parameters
           __m Whether the buffer can read, or write, or both.

       Initializes sb using the mode from __m, and passes &sb to the base class initializer. Does
       not allocate any buffer.

       That's a lie. We initialize the base class with NULL, because the string class does its
       own memory management.

       Definition at line 756 of file sstream.

   template<typename _CharT , typename _Traits , typename _Alloc > std::basic_stringstream<
       _CharT, _Traits, _Alloc >::basic_stringstream (const __string_type & __str,
       ios_base::openmode __m = ios_base::out | ios_base::in) [inline],  [explicit]
       Starts with an existing string buffer.

       Parameters
           __str A string to copy as a starting buffer.
           __m Whether the buffer can read, or write, or both.

       Initializes sb using __str and __m, and passes &sb to the base class initializer.

       That's a lie. We initialize the base class with NULL, because the string class does its
       own memory management.

       Definition at line 772 of file sstream.

   template<typename _CharT , typename _Traits , typename _Alloc > std::basic_stringstream<
       _CharT, _Traits, _Alloc >::~basic_stringstream () [inline]
       The destructor does nothing. The buffer is deallocated by the stringbuf object, not the
       formatting stream.

       Definition at line 783 of file sstream.

Member Function Documentation

   template<typename _CharT , typename _Traits , typename _Alloc > __stringbuf_type*
       std::basic_stringstream< _CharT, _Traits, _Alloc >::rdbuf () const [inline]
       Accessing the underlying buffer.

       Returns
           The current basic_stringbuf buffer.

       This hides both signatures of std::basic_ios::rdbuf().

   template<typename _CharT , typename _Traits , typename _Alloc > __string_type
       std::basic_stringstream< _CharT, _Traits, _Alloc >::str () const [inline]
       Copying out the string buffer.

       Returns
           rdbuf()->str()

       Definition at line 831 of file sstream.

   template<typename _CharT , typename _Traits , typename _Alloc > void std::basic_stringstream<
       _CharT, _Traits, _Alloc >::str (const __string_type & __s) [inline]
       Setting a new buffer.

       Parameters
           __s The string to use as a new sequence.

       Calls rdbuf()->str(s).
