Chama
basic_ios::swap(rhs) para trocar todos os membros de dados da classe base, exceto para rdbuf() e troca os valores dos contadores gcount() entre *this e rhs. Esta função swap é protegido: chama-se pelas funções de swap das classes de fluxo de entrada de swap std::basic_ifstream e std::basic_istringstream, que sabe como fazer corretamente trocar os streambuffers associados.Original:
Calls
basic_ios::swap(rhs) to swap all data members of the base class except for rdbuf(), and swaps the values of the gcount() counters between *this and rhs. This swap function is protected: it is called by the swap functions of the swappable input stream classes std::basic_ifstream and std::basic_istringstream, which know how to correctly swap the associated streambuffers.The text has been machine-translated via Google Translate.
