std::list<T,Allocator>::push_back
From cppreference.com
void push_back( const T& value ); |
(1) | |
void push_back( T&& value ); |
(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 (which can be due to Allocator::allocate() or element copy/move constructor/assignment), this function has no effect (strong exception guarantee).
Example
Run this code
#include <iomanip>
#include <iostream>
#include <string>
#include <list>
int main()
{
std::list<std::string> letters;
letters.push_back("abc");
std::string s{"def"};
letters.push_back(std::move(s));
std::cout << "std::list letters holds: ";
for (auto&& e : letters)
std::cout << std::quoted(e) << ' ';
std::cout << "\nMoved-from string s holds: " << std::quoted(s) << '\n';
}
Possible output:
std::list letters holds: "abc" "def"
Moved-from string s holds: ""
