std::deque::emplace_front(3) C++ Standard Libary std::deque::emplace_front(3) NAME std::deque::emplace_front - std::deque::emplace_front Synopsis template< class... Args > (since C++11) void emplace_front( Args&&... args ); (until C++17) template< class... Args > (since C++17) reference emplace_front( Args&&... args ); Inserts a new element to the beginning of the container. The element is constructed through std::allocator_traits::construct, which typically uses place- ment-new to construct the element in-place at the location provided by the con- tainer. The arguments args... are forwarded to the constructor as std::for- ward<Args>(args).... All iterators (including the end() iterator) are invalidated. No refer- ences are invalidated. Parameters args - arguments to forward to the constructor of the element Type requirements - T (the container's element type) must meet the requirements of Emplace- Constructible. Return value (none) (until C++17) A reference to the inserted element. (since C++17) Complexity Constant. Exceptions If an exception is thrown for any reason, this function has no effect (strong exception safety guarantee).
