class
<sstream>
std::wstringbuf
typedef basic_stringbuf<wchar_t> wstringbuf;
String stream buffer (wide)
Stream buffer to read from and write to wstring objects.
Objects of this class maintain internally a sequence of wide characters that they use as their associated input sequence and/or associated output sequence. The internal sequence can be initialized from a wstring object, or copied to one, using member str.
Access to the internal sequence of characters is given to streams by means of the interface offered by the virtual members inherited from wstreambuf that are overriden in this class:
Public member functions
Note: The references to the members of its basic template (basic_stringbuf) are linked here.
- (constructor)
- Construct object (public member function
)
- str
- Get/set content (public member function
)
Public member functions inherited from wstreambuf
Locales:
- pubimbue
- Imbue locale (public member function
)
- getloc
- Get current locale (public member function
)
Buffer management and positioning:
- pubsetbuf
- Set buffer array (public member function
)
- pubseekoff
- Set internal position pointer to relative position (public member function
)
- pubseekpos
- Set internal position pointer to absolute position (public member function
)

)
Input functions (get):
- in_avail
- Get number of character available to read (public member function
)
- snextc

)
Protected virtual function overrides
Note: The references to the members of its basic template (basic_stringbuf) are linked here.
- setbuf
- Set buffer (protected virtual member function
)
- seekoff
- Set position pointer to relative position (protected virtual member function
)
- seekpos
- Set position pointer to absolute position (protected virtual member function
)
- underflow
- Get character (protected virtual member function
)
- pbackfail
- Put character back (protected virtual member function
)
- overflow
- Put character (protected virtual member function
)
The class also inherits other protected members that are non-virtual or not overridden. See base class wstreambuf for more details.
