Indice

[modifica]Categorie di iteratori

Ci sono cinque tipi di iteratori: InputIterator, OutputIterator, ForwardIterator, BidirectionalIterator e RandomAccessIterator.
Original:
There are five kinds of iterators: InputIterator, OutputIterator, ForwardIterator, BidirectionalIterator, and RandomAccessIterator.

Invece di essere definita da specifici tipi, ciascuna categoria di iteratore è definito dalle operazioni che possono essere eseguite su di esso. Questa definizione significa che qualsiasi tipo che supporta le operazioni necessarie possono essere utilizzati come un iteratore - per esempio, un puntatore supporta tutte le operazioni richieste da RandomAccessIterator, quindi un puntatore può essere utilizzato ovunque un RandomAccessIterator è previsto.
Original:
Instead of being defined by specific types, each category of iterator is defined by the operations that can be performed on it. This definition means that any type that supports the necessary operations can be used as an iterator -- for example, a pointer supports all of the operations required by RandomAccessIterator, so a pointer can be used anywhere a RandomAccessIterator is expected.

Le cinque categorie iteratore possono essere organizzati in una gerarchia, in cui le categorie iteratore più potenti (ad es RandomAccessIterator) supportano le operazioni di categorie meno potenti (ad esempio InputIterator):
Original:
The five iterator categories can be organized into a hierarchy, where more powerful iterator categories (e.g. RandomAccessIterator) support the operations of less powerful categories (e.g. InputIterator):
