jumpingSupported
true
if this IviDataSource supports jumping, false
otherwise.
Override this to true
if pseudo-fast scrolling via jumps is supported. See PagingConfig.jumpThreshold for details.
A jump occurs when a RecyclerView
scrolls through a number of placeholders defined by PagingConfig.jumpThreshold and triggers a load with LoadType.REFRESH.
This property is included here to facilitate the integration with the Android Paging library.
