NAME¶

std::basic_stringbuf::operator= - std::basic_stringbuf::operator=

Synopsis¶

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

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 <iostream>
#include <sstream>
#include <string>

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 = ""
