That is, + * it is essentially an <b>ordered map</b> that can also be used + * like a list. + * + * A Collection has an internal iterator just like a PHP array. In addition, + * a Collection can be iterated with external iterators, which is preferable. + * To use an external iterator simply use the foreach language construct to + * iterate over the collection (which calls {@link getIterator()} internally) or + * explicitly retrieve an iterator though {@link getIterator()} which can then be + * used to iterate over the collection. + * You can not rely on the internal iterator of the collection being at a certain + * position unless you explicitly positioned it before. Prefer iteration with + * external iterators. + * + * @since 2.0 + * @author Guilherme Blanco <guilhermeblanco@hotmail.com> + * @author Jonathan Wage <jonwage@gmail.com> + * @author Roman Borschel <roman@code-factory.org> + */ +interface Collection extends Countable, IteratorAggregate, ArrayAccess +{ + /** + * Adds an element at the end of the collection. + * + * @param mixed $element The element to add. + * + * @return boolean Always TRUE. + */ + public function add($element);
