Starts the creation of a compiled RepositoryPresenter. A compiled presenter work with item objects: firstly, the repository value is converted to a list of item objects, the list size determining the item count; then the layout resources, item IDs, binding, and change detection are all based on the individual item objects. Client code supplies the logic for each aspect of the presenter, such as:

• .layoutForItem(Function<T, Integer>) selects the layout resource ID for each item object;
• .stableIdForItem(Function<T, Long>) provides a stable ID per item object;
• .bindWidth(Binder<T, View>) renders the item data onto the view;
• .forCollection(Function<V, List<T>>) specifies the method to convert the repository value (of type V) to an item list (shortcuts are provided for repository values of type T, List<T>, Result<T> or Result<List<T>> that can be converted in typical ways).

Parameters:

type - The type of the item objects.
