Constructs new stream object.
1) Initializes with streambuf sb. The base classes are initialized as basic_istream<CharT,Traits>(sb) and basic_ostream<CharT,Traits>(sb). After the call rdbuf() == sb and gcount() == 0
2) Copy construction is not allowed.
3) Move constructor: move-constructs the first base class
basic_istream as
basic_istream<CharT,Traits>
(std::
move
(rhs)
)
;
, which in turn move-constructs and initializes the virtual base std::basic_ios. The initialization of the other base, basic_ostream, is implementation-defined (e.g., a protected default constructor may be added to std::basic_ostream, which does nothing) because move-construction cannot use rhs twice. This move constructor is protected: it is called by the move constructors of the derived stream classes std::basic_fstream and std::basic_stringstream
Parameters
| sb | - | streambuf to initialize with |
| other | - | another stream to initialize with |
