std::basic_iostream::basic_iostream
explicit basic_iostream( std::basic_streambuf<CharT,Traits>* sb ); | (1) | ? |
|---|---|---|
basic_iostream( const basic_iostream& other ) = delete; | (2) | (since C++11) |
protected: basic_iostream( basic_iostream&& other ); | (3) | (since C++11) |
构造新的流对象。
1%29用Streambuf初始化sb基类初始化为basic_istream<CharT,Traits>(sb)和basic_ostream<CharT,Traits>(sb).打完电话后rdbuf() == sb和gcount() == 0...
2%29复制构造是不允许的。
3%29移动构造函数：移动-构造第一个基类basic_istream如basic_istream<CharT,Traits>(std::move(rhs));，然后移动-构造并初始化虚拟基。std::basic_ios另一个基地的初始化，basic_ostream，是实现定义的%28e。，则可以将受保护的默认构造函数添加到std::basic_ostream，因为移动构造不能使用rhs两次。此移动构造函数是受保护的：它由派生流类的移动构造函数调用。std::basic_fstream和std::basic_stringstream在它们移动之前-构造和关联流缓冲区。
