basic_osyncstream& operator=( std::basic_osyncstream&& other ); | (since C++20) |
Move-assigns a synchronized output stream:
Move-assigns the wrapped std::basic_syncbuf from the corresponding member of other (after this move-assignment, other.get_wrapped() returns a null pointer and destruction of other produces no output; any pending buffered output will be emitted) and move-assigns the base std::basic_ostream (this swaps all stream state variables except for rdbuf between *this and other).
| other | - | another synchronized output stream to move from |
*this.
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 3867 | C++20 | the move assignment operator was noexcept, butstd::basic_syncbuf's move assignment operator is not | removed noexcept |
constructs a basic_osyncstream object (public member function) |
|
destroys the basic_osyncstream and emits its internal buffer (public member function) |
|
calls emit() on the underlying basic_syncbuf to transmit its internal data to the final destination (public member function) |
