      • didDeleteItemsWithIdentifiers

        void didDeleteItemsWithIdentifiers​(NSArray<java.lang.String> deletedItemIdentifiers)
        Delete existing items. No-op if the item was unknown.

        void didUpdateItems​(NSArray<?> updatedItems)
        Send updates to existing items, or insert new items.

      • finishEnumeratingChangesUpToSyncAnchorMoreComing

        void finishEnumeratingChangesUpToSyncAnchorMoreComing​(NSData anchor,
                                                      boolean moreComing)
        Call the following method every so often while sending changes, particularly while enumerating changes to NSFileProviderWorkingSetContainerItemIdentifier. If the device reboots during an enumeration, it would later resume starting at the latest known sync anchor. It is expected that the sync anchor passed here be different than the sync anchor that the enumeration started at, unless the client was already up to date on all the changes on the server, and didn't have any pending updates or deletions. Additionally, if the client is up to date on all the changes on the server it should set moreComing to NO. Sync anchor data is limited to 500 bytes. Setting a larger anchor has the same effect as calling finishEnumeratingWithError with an expired sync anchor error.

      • finishEnumeratingWithError

        void finishEnumeratingWithError​(NSError error)
        If the enumeration fails with NSFileProviderErrorSyncAnchorExpired, we will drop all cached data and start the enumeration over starting with sync anchor nil.
