BatchingListUpdateCallback

public class BatchingListUpdateCallback
extends Object implements ListUpdateCallback

Wraps a ListUpdateCallback callback and batches operations that can be merged.

For instance, when 2 add operations comes that adds 2 consecutive elements, BatchingListUpdateCallback merges them and calls the wrapped callback only once.

This is a general purpose class and is also used by DiffResult and SortedList to minimize the number of updates that are dispatched.

If you use this class to batch updates, you must call dispatchLastEvent() when the stream of update events drain.
