std::basic_ostringstream::operator=

From cppreference.com
basic_ostringstream& operator=( basic_ostringstream&& other );
(since C++11)

Move assigns the string stream other to *this, effectively move-assigning both the std::basic_ostream base class and the associated std::basic_stringbuf.

Note that the base class move assignment swaps all stream state variables (except for rdbuf) between *this and other.

Parameters

other - string stream to move from

Return value

*this
