1)
将赋值运算符：将内容
rhs*this。移动后，lhs有关联的字符串，开模，语言环境，和所有其他国家持有的rhs。的六个指针std::basic_streambuflhs保证是从相应的指针在空值的移动，从rhs除非不同.原文：
Move assignment operator: Moves the contents of
rhs into *this. After the move, lhs has the associated string, the open mode, the locale, and all other state formerly held by rhs. The six pointers of std::basic_streambuf in lhs are guaranteed to be different from the corresponding pointers in the moved-from rhs unless null.2)
拷贝赋值运算符被删除;
basic_stringbuf是不CopyAssignable.原文：
The copy assignment operator is deleted;
basic_stringbuf is not CopyAssignable.目录 |

*this
[编辑] 示例
#include <sstream> #include <string> #include <iostream> int main() { std::istringstream one("one"); std::ostringstream two("two"); std::cout << "Before move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; *one.rdbuf() = std::move(*two.rdbuf()); std::cout << "Before move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; }
输出：
Before move, one = "one" two = "two" Before move, one = "two" two = ""
