Comparar tuple objetos para maior ou igual.

template<class T1, class T2, ..., class TN,
    class U1, class U2, ..., class UN>
    bool operator>=(const tuple<T1, T2, ..., TN>& tpl1,
    const tuple<U1, U2, ..., UN>& tpl2);

Parâmetros

TN
O tipo de elemment enésima tupla.

Comentários

A função retornará !(tpl1 < tpl2).
