public interface OrderedCollectionChangeRecord implements ChangeRecord

Purpose: Provide public API to the OrderedCollectionChangeRecord.

Description: OrderedCollections, used in TopLink SDK, must be tracked differently from regulat Collections. As the objects in the collection have a particular index which must be stored. This class stores the objects which must be written into the collection and the indexes they must be written in at. Inserting a new element at the beginning of the list will result in the intire list being stored in the change set as the index of all other objects has changed. Everything after the remove index will be remove.
