template< class... Args >
iterator emplace( const_iterator pos, Args&&... args );
(a partir do C++ 11)
Insere um novo elemento para o recipiente diretamente antes pos. O elemento é construído no local, ou seja, nenhuma cópia ou operações de movimentação são executadas. O construtor do elemento é chamado com o std::forward<Args>(args)... argumentos. O tipo de elemento deve ser EmplaceConstructible, MoveInsertable and MoveAssignable.
Original:
Inserts a new element into the container directly before pos. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element is called with the arguments std::forward<Args>(args).... The element type must be EmplaceConstructible, MoveInsertable and MoveAssignable.

If the new size() is greater than capacity(), all iterators and references are invalidated. Otherwise, only the iterators and references after the added element are invalidated.
