ムーブコンストラクタは
basic_ios<CharT, Traits>::move(rhs)からrdbuf()に、rhsを除き、すべてのbasic_iosメンバーを移動する*this使用しています。このムーブコンストラクタは保護されています：それは、可動出力ストリームクラスのムーブコンストラクタstd::basic_ofstreamとstd::basic_ostringstream、正しく関連付けられたストリームバッファを移動する方法を知っているから呼び出されます.Original:
The move constructor uses
basic_ios<CharT, Traits>::move(rhs) to move all basic_ios members, except for the rdbuf(), from rhs into *this. This move constructor is protected: it is called by the move constructors of movable output stream classes std::basic_ofstream and std::basic_ostringstream, which know how to correctly move the associated streambuffer.The text has been machine-translated via Google Translate.

#include <sstream> #include <utility> #include <iostream> int main() { // std::ostream myout(std::cout); // ERROR: copy ctor is deleted std::ostream myout(std::cout.rdbuf()); // OK: shares buffer with cout // std::ostream s2(std::move(std::ostringstream() << 7.1)); // ERROR: move constructor // is protected std::ostringstream s2(std::move(std::ostringstream() << 7.1)); // OK: move ctor called // through the derived class myout << s2.str() << '\n'; }
Output:
