The Zend_Feed_Abstract class is an abstract class representing feeds.
Zend_Feed_Abstract implements two core PHP 5 interfaces: ArrayAccess and Iterator. In both cases the collection being treated as an array is considered to be the entry collection, such that iterating over the feed takes you through each of the feed.s entries.
