>classbasic_ostringstream :publicbasic_ostream<CharT, Traits>; 类模板std::basic_ostringstream实现基于字符串的流上的输出操作。它相当于存储一个std::basic_string的实例,并在它之上进行输出操作。 该类实际上在低层将一个std::basic_stringbuf的原生字符串设备实现包装到std::basic_ostream的高层接口中。它提供...
ostrstream从 C++98 起被弃用并从 C++26 起被移除,推荐用std::ostringstream、std::ospanstream(C++23 起)和boost::iostreams::array_sink替代。 成员函数 (构造函数) 构造ostrstream对象,部分情况下会分配缓冲区 (公开成员函数) (析构函数) [虚] 析构ostrstream对象,部分情况下会解分配缓冲区 ...

std::ostringstream 继承了 ios_base 类,而 ios_base 使用了 std::locale。 std::locale 构造函数、赋值函数会对 _M_impl 成员进行指针赋值,即 _M_impl 是全局共享的。 std::locale 构造函数、赋值函数会执行引用计数增加(即执行_M_impl->_M_add_reference()),析构函数会执行引用计数递减(即执行_M_impl...
