The IteratorIterator class

(PHP 5 >= 5.1.0, PHP 7, PHP 8)

Einführung

This iterator wrapper allows the conversion of anything that is Traversable into an Iterator. It is important to understand that most classes that do not implement Iterators have reasons as most likely they do not allow the full Iterator feature set. If so, techniques should be provided to prevent misuse, otherwise expect exceptions or fatal errors.

Klassenbeschreibung

class IteratorIterator implements OuterIterator {
/* Methoden */
public function __construct(Traversable $iterator, ?string $class = null)
public function current(): mixed
public function getInnerIterator(): ?Iterator
public function key(): mixed
public function next(): void
public function rewind(): void
public function valid(): bool
}

Anmerkungen

Hinweis:

This class permits access to methods of the inner iterator via the __call magic method.
