Protocols

Implement this protocol to provide data to an IGListAdapter.

Conform to IGListAdapterDelegate to receive display events for objects in a list.

A protocol that receives events about IGListAdapterUpdater operations.

The collection context provides limited access to the collection-related information that section controllers need for operations like sizing, dequeing cells, insterting, deleting, reloading, etc.

The IGListDiffable protocol provides methods needed to compare the identity and equality of two objects.

Implement this protocol to receive display events for an section controller when it is on screen.

Implement this protocol to receive display events for an section controller when it is on screen.

Implement this protocol in order to be used within the IGListKit data infrastructure and be registered for use in an IGListAdapter. An IGListSectionType conforming object represents a single instance of an object in a collection of objects.

The infrastructure uses each IGListSectionType conforming object as a view model to populate and control cells as part of a section in a UICollectionView. IGListSectionType objects should be architected without knowledge of global state of the list in which they are contained.

Index paths are used as a convenience for communicating the section index to each section object without allowing each section to mutate its own position within a list. The row of an index path can be directly mapped to a cell within an IGListSectionType conforming object.

A delegate that can receive selection events on an IGListSingleSectionController.

Conform to this protocol to provide information about a list’s supplementary views. This data is used in IGListAdapter which then configures and maintains a UICollectionView. The supplementary API reflects that in UICollectionView, UICollectionViewLayout, and UICollectionViewDataSource.

Implement this protocol in order to handle both section and row based update events. Implementation should forward or coalesce these events to a backing store or collection.

Implement this protocol to receive working range events for a list.

The working range is a range near the viewport in which you can begin preparing content for display. For example, you could begin decoding images, or warming text caches.
