swap(std::basic_stringbuf)(C++11)
 
(dal C++11)
std::basic_stringbuf& operator=( const std::basic_stringbuf& rhs ) = delete;
1)
Spostare operatore di assegnazione: sposta il contenuto di rhs in *this. Dopo lo spostamento, lhs ha la stringa associata, la modalità di apertura, il locale, e tutto altro stato in precedenza detenuto da rhs. I sei indicatori di std::basic_streambuf in lhs sono garantiti per essere diversi dai puntatori corrispondenti nel mosso-da rhs a meno che nulla.
Original:
Move assignment operator: Moves the contents of rhs into *this. After the move, lhs has the associated string, the open mode, the locale, and all other state formerly held by rhs. The six pointers of std::basic_streambuf in lhs are guaranteed to be different from the corresponding pointers in the moved-from rhs unless null.

#include <sstream>
#include <string>
#include <iostream>
 
int main()
{
 
    std::istringstream one("one");
    std::ostringstream two("two");
 
    std::cout << "Before move, one = \"" << one.str() << '"'
              << " two = \"" << two.str() << "\"\n";
 
    *one.rdbuf() = std::move(*two.rdbuf());
 
    std::cout << "Before move, one = \"" << one.str() << '"'
              << " two = \"" << two.str() << "\"\n";
}

Output:

Before move, one = "one" two = "two"
Before move, one = "two" two = ""
