std::basic_iostream<CharT,Traits>::basic_iostream
explicit basic_iostream( std::basic_streambuf<CharT,Traits>* sb ); |
(1) | |
basic_iostream( const basic_iostream& other ) = delete; |
(2) | (since C++11) |
protected: basic_iostream( basic_iostream&& other ); |
(3) | (since C++11) |
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
before they move-construct and associate the stream buffer.
Parameters
sb | - | streambuf to initialize with |
other | - | another stream to initialize with |
