Mova construtor: move-constrói a classe base primeiro
basic_istream como basic_istream<CharT,Traits>(std::move(rhs));, que por sua vez move-constrói e inicializa o std::basic_ios base virtual. A inicialização da outra base, basic_ostream, é definida pela implementação (por exemplo, um construtor padrão protegido pode ser adicionado ao std::basic_ostream, que não faz nada) porque mover-construção não pode usar rhs duas vezes. Esse construtor movimento é protegido: ele é chamado pelos construtores movimento das classes de fluxo derivados std::basic_fstream e std::basic_stringstream antes de mover-construir e associar o buffer de fluxo.Original:
Move constructor: move-constructs the first base class
basic_istream as basic_istream<CharT,Traits>(std::move(rhs));, which in turn move-constructs and initializes the virtual base std::basic_ios. The initialization of the other base, basic_ostream, is implementation-defined (e.g., a protected default constructor may be added to std::basic_ostream, which does nothing) because move-construction cannot use rhs twice. This move constructor is protected: it is called by the move constructors of the derived stream classes std::basic_fstream and std::basic_stringstream before they move-construct and associate the stream buffer.The text has been machine-translated via Google Translate.
