The class template std::basic_stringstream implements input/output operations on memory (std::basic_string) based streams. It essentially wraps a raw string device implementation (std::basic_stringbuf) into a higher-level interface (std::basic_iostream). The complete interface to unique std::basic_stringbuf members is provided.
Two specializations for common character types are also defined:
| Defined in header  <sstream> | |
| Type | Definition | 
| stringstream | basic_stringstream<char> | 
| wstringstream | basic_stringstream<wchar_t> |
