T* data();
(dal C++11)
const T* data() const;
(dal C++11)
Restituisce il puntatore alla matrice sottostante che funge da elemento di memoria. Il puntatore è tale che [data(); data() + size()) intervallo è sempre un intervallo valido, anche se il contenitore è vuoto.
Original:
Returns pointer to the underlying array serving as element storage. The pointer is such that range [data(); data() + size()) is always a valid range, even if the container is empty.
