std::basic_stringbuf

Defined in header <sstream>
template<     class charT,     class Traits = std::char_traits<CharT>,     class Allocator = std::allocator<CharT> > class basic_stringbuf : public std::basic_streambuf<CharT, Traits>

std::basic_stringbuf is a specialization of Template:cpp whose associated character sequence is a memory-resident sequence of arbitrary characters, which can be initialized from or made available as an instance of Template:cpp.

Typical implementations of std::basic_stringbuf hold an object of type Template:cpp directly as a data member and use it as both the controlled character sequence (the array where the six pointers of Template:cpp are pointing to) and as the associated character sequence (the source of characters for all input operations and the target for the output). In addition, a typical implementation holds a data member of type Template:cpp to indicate the status of the stream (input-only, output-only, or input/output).

Two specializations for common character types are also defined:

Member functions

Public member functions
(constructor)	constructs a basic_stringbuf object (public member function)
operator= (C++11)	assigns a basic_stringbuf object (public member function)
swap (C++11)	swaps two basic_stringbuf objects (public member function)
str	replaces or obtains a copy of the associated character string (public member function)
Protected member functions
underflow [virtual]	returns the next character available in the input sequence (virtual protected member function)
pbackfail [virtual]	puts a character back into the input sequence (virtual protected member function)
overflow [virtual]	appends a character to the output sequence (virtual protected member function)
setbuf [virtual]	attempts to replace the controlled character sequence with an array (virtual protected member function)
seekoff [virtual]	repositions the next pointer in the input sequence, output sequence, or both, using relative addressing (virtual protected member function)
seekpos [virtual]	repositions the next pointer in the input sequence, output sequence, or both using absolute addressing (virtual protected member function)

Non-member functions

std::swap(std::basic_stringbuf) (C++11)

specializes the Template:cpp algorithm (function template)
