pack-priv Class CollectionIndex

Located in compilation unit of org.apache.html.dom.HTMLCollectionImpl.

extends Object
Class Inheritance
CollectionImpl#item must traverse down the tree and decrement the index until it matches an element who's index is zero. Since integers are passed by value, this class servers to pass the index into each recursion by reference. It encompasses all the operations that need be performed on the index, although direct access is possible.
