(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, 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.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 << "Before move, one = \"" << one.str() << '"' << " two = \"" << two.str() << "\"\n"; }
Output:
Before move, one = "one" two = "two" Before move, one = "two" two = ""
