tie-Funktion
Macht tuple aus den Elementverweisen.
template<class T1, class T2, ..., class TN>
tuple<T1&, T2&, ..., TN&>
tie(T1& t1, T2& t2, ..., TN& tN);
Parameter
- TN
Der Basistyp des N-ten Tupelelements.
Hinweise
Die Vorlagenfunktion gibt tuple<T1&, T2&, ..., TN&>(t1, t2, ..., tN) zurück.
Beispiel
// std_tr1__tuple__tie.cpp
// compile with: /EHsc
#include <tuple>
#include <iostream>
typedef std::tuple<int, double, int, double> Mytuple;
int main()
{
Mytuple c0(0, 1, 2, 3);
// display contents " 0 1 2 3"
std::cout << " " << std::get<0>(c0);
std::cout << " " << std::get<1>(c0);
std::cout << " " << std::get<2>(c0);
std::cout << " " << std::get<3>(c0);
std::cout << std::endl;
int v4 = 4;
double v5 = 5;
int v6 = 6;
double v7 = 7;
std::tie(v4, v5, v6, v7) = c0;
// display contents " 0 1 2 3"
std::cout << " " << v4;
std::cout << " " << v5;
std::cout << " " << v6;
std::cout << " " << v7;
std::cout << std::endl;
return (0);
}
