| (1) | |||
| (2) | (since C++11) |
Appends the given element value
to the end of the container.
1) The new element is initialized as a copy of
value
. 2)
value
is moved into the new element.No iterators or references are invalidated.
Parameters
value | - | the value of the element to append |
Type requirements | ||
- T must meet the requirements of CopyInsertable in order to use overload (1). | ||
- T must meet the requirements of MoveInsertable in order to use overload (2). |
Return value
(none).
Complexity
Constant.
Exceptions
If an exception is thrown, this function has no effect (strong exception guarantee).
Example
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | #include <list> #include <iostream> #include <iomanip> int main() { std::list<std::string> numbers; numbers.push_back( "abc" ); std::string s = "def" ; numbers.push_back(std::move(s)); std::cout << "list holds: " ; for (auto&& i : numbers) std::cout << std::quoted(i) << ' ' ; std::cout << "\nMoved-from string holds " << std::quoted(s) << '\n' ; } |
Output:
1 2 | list holds: "abc" "def" Moved-from string holds "" |
