Method that's invoked when operation goes up from the recursion and BPlusTree.Get.isFinished() returns false. Either finishes the operation or locks the page for further processing on another level.

Returns BPlusTree.Result.FOUND if operation has finished and BPlusTree.Get.isFinished() returns true now.

Returns BPlusTree.Result.RETRY if operation should be retried.

Returns BPlusTree.Result.NOT_FOUND if operation has added the page to tail, meaning that operation can't be finished on current level.

pageId - Page ID.

page - Page pointer.

backId - Back page ID.
