Defined in header <locale>
protected: ~collate();
Distrugge un aspetto std::collate. Questo distruttore è protetta e virtuale (a causa di distruttore della classe base essere virtuale). Un oggetto di tipo std::collate, come la maggior parte sfaccettature, possono essere distrutti solo quando l'oggetto std::locale ultimo che implementa questo aspetto va fuori di portata, o se una classe definita dall'utente è derivato da std::collate e implementa un distruttore pubblico.
Original:
Destructs a std::collate facet. This destructor is protected and virtual (due to della classe base destructor being virtual). An object of type std::collate, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined class is derived from std::collate and implements a public destructor.
