Interface for item reuse strategies.

Notice: Child items will be rendered in the order they are provided by the returned iterator, so it is important that the strategy preserve this order

Method Detail


<T> Iterator<Item<T>> getItems(IItemFactory<T> factory,
                               Iterator<IModel<T>> newModels,
                               Iterator<Item<T>> existingItems)
Returns an iterator over items that will be added to the view. The iterator needs to return all the items because the old ones are removed prior to the new ones added.

Type Parameters:
T - type of Item
factory - implementation of IItemFactory
newModels - iterator over models for items
existingItems - iterator over child items
iterator over items that will be added after all the old items are moved.
