Reference
<fstream>
ifstream
operator=
public member function
<fstream>
std::
ifstream
::operator=
copy (1)
ifstream& operator= (const ifstream&) = delete;
move (2)
ifstream& operator= (ifstream&& rhs);
Move assignment
Acquires the contents of
rhs
, by move-assigning its members and base classes.
Parameters
rhs
Another
ifstream
object.
Return Value
*this
Data races
Modifies both stream objects (
*this
and
rhs
).
Exception safety
No-throw guarantee:
this member function never throws exceptions.
