class raw_storage_iterator

    : public std::iterator<std::output_iterator_tag, void, void, void, void>;
Die Ausgabeiterator std::raw_storage_iterator ermöglicht Standardalgorithmen um Ergebnisse in initialisierten Speicher zu speichern. Wenn der Algorithmus ein Objekt vom Typ T der dereferenziert Iterator schreibt, ist das Objekt copy-gebaut in den Standort in der initialisierten Speicher, auf den der Iterator. Der Template-Parameter OutputIt ist jede Art, die dich Anforderungen OutputIterator entspricht und operator* definiert ein Objekt, für das operator& gibt ein Objekt vom Typ T* zurückzukehren. Üblicherweise wird die Aktivität als T* OutputIt verwendet .
Original:
The output iterator std::raw_storage_iterator makes it possible for standard algorithms to store results in uninitialized memory. Whenever the algorithm writes an object of type T to the dereferenced iterator, the object is copy-constructed into the location in the uninitialized storage pointed to by the iterator. The template parameter OutputIt is any type that meets thee requirements of OutputIterator and has operator* defined to return an object, for which operator& returns an object of type T*. Usually, the type T* is used as OutputIt.
