std::basic_stringbuf<CharT,Traits,Allocator>::operator= - cppreference.com (original) (raw)
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.
The copy assignment operator is deleted;
basic_stringbufis not CopyAssignable.
[edit] Parameters
| rhs | - | another basic_stringbuf that will be moved from |
|---|
[edit] Return value
*this
[edit] Example
#include #include #include 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 = ""
