template< class... Args > iterator emplace( const_iterator pos, Args&&... args );		(C + + 11以来)

直接挿入pos前にコンテナに新しい要素。要素はその場で構成され、操作が実行されないコピーや移動、すなわちません。要素のコンストラクタは引数std::forward<Args>(args)...で呼び出されます。要素型はEmplaceConstructible, MoveInsertable and MoveAssignableでなければなりません.

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.

複雑

Linear in the distance between pos and end of the container.

例外

例外は（コンストラクタなどで）スローされた場合、この関数は（強い例外保証）と呼ばれることはなかったかのように、容器は、変更されない.

Original:

If an exception is thrown (e.g. by the constructor), the container is left unmodified, as if this function was never called (strong exception guarantee).
