# std::basic_stringbuf<CharT,Traits,Allocator>::operator=

From cppreference.com
< cpp‎ | io‎ | basic stringbuf

std::basic_stringbuf& operator=( std::basic_stringbuf&& rhs ); | (1) | (since C++11)
std::basic_stringbuf& operator=( const std::basic_stringbuf& rhs ) = delete; | (2) |

1) Move assignment operator: Moves the contents of `rhs` into `*this`. After the move, `*this` 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 `*this` are guaranteed to be different from the corresponding pointers in the moved-from `rhs` unless null.
2) The copy assignment operator is deleted; `basic_stringbuf` is not CopyAssignable.

### Parameters

rhs | - | another `basic_stringbuf` that will be moved from

### Return value

`*this`

### Example

Run this code

    #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 << "After move, one = \"" << one.str() << '"'
                  << " two = \"" << two.str() << "\"\n";
    }

Output:

    Before move, one = "one" two = "two"
    After move, one = "two" two = ""
