Method Detail

calculateDiff

public static <A extends <any>,Model,Item extends IItem> DiffUtil.DiffResult calculateDiff(A adapter,
                                                                                           java.util.List<Item> items,
                                                                                           DiffCallback<Item> callback,
                                                                                           boolean detectMoves)

This method will compute a androidx.recyclerview.widget.DiffUtil.DiffResult based on the given adapter, and the list of new items.

It automatically collapses all expandables (if enabled) as they are not supported by the diff util, pre sort the items based on the comparator if available, map the new item types for the FastAdapter then calculates the androidx.recyclerview.widget.DiffUtil.DiffResult using the DiffUtil.

As the last step it will replace the items inside the adapter with the new set of items provided.

Type Parameters:

A - The adapter type, whereas A extends ModelAdapter

Model - The model type we work with

Item - The item type kept in the adapter

Parameters:

adapter - the adapter containing the current items.

items - the new set of items we want to put into the adapter

callback - the callback used to implement the required checks to identify changes of items.

detectMoves - configuration for the DiffUtil#calculateDiff(DiffUtil.Callback, boolean) method

Returns:

the androidx.recyclerview.widget.DiffUtil.DiffResult computed.

set

public static <A extends <any>,Model,Item extends IItem> A set(A adapter,
                                                               DiffUtil.DiffResult result)

Dispatches a androidx.recyclerview.widget.DiffUtil.DiffResult to the given Adapter.

Parameters:

adapter - the adapter to dispatch the updates to

result - the computed androidx.recyclerview.widget.DiffUtil.DiffResult

Returns:

the adapter to allow chaining
