Eccezioni

noexcept specification:  (dal C++11)

noexcept(     noexcept(swap(std::declval<T0&>>(), std::declval<T0&>()))&&     noexcept(swap(std::declval<T1&>>(), std::declval<T1&>()))&&     noexcept(swap(std::declval<T2&>>(), std::declval<T2&>()))&&     ... )

Esempio

#include <iostream>#include <tuple>#include <string>   int main(){std::tuple<int, std::string, float> p1, p2; p1 =std::make_tuple(10, "test", 3.14); p2.swap(p1);std::cout<<"("<< std::get<0>(p2)<<", "<< std::get<1>(p2)<<", "<< std::get<2>(p2)<<")\n";}

Output:

(10, test, 3.14)
