@PublicSpi
public interface ItemChangeFilter

An implementor of this interfaces checks if any of changed items may affect a built forest fragment. The implementor may detect only changes those are recorded to ItemTracker

Here is the basic implementation:

   return itemIds.stream().anyMatch(itemId ->
     // return true if a change of the item may affect the forest fragment
     );
 

If the forest fragment may depend on changes those are not reported to the ItemTracker You have to implement UpdateChecker
