The IteratorIterator class

(PHP 5 >= 5.1.0)

简介

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.

}

IteratorIterator::__construct — Create an iterator from anything that is traversable
IteratorIterator::current — Get the current value
IteratorIterator::getInnerIterator — Get the inner iterator
IteratorIterator::key — Get the key of the current element
IteratorIterator::next — Forward to the next element
IteratorIterator::rewind — Rewind to the first element
IteratorIterator::valid — Checks if the iterator is valid
