basic_istringstream (std::basic_string) . (basic_stringbuf) (basic_istream). basic_stringbuf .
:
The class template basic_istringstream implements input operations on memory (std::basic_string) based streams. It essentially wraps a raw string device implementation (basic_stringbuf) into a higher-level interface (basic_istream). The complete interface to unique basic_stringbuf members is provided.
