Class DeleteSet

java.lang.Object

io.keikai.doc.collab.utils.DeleteSet

public class DeleteSet
extends java.lang.Object

We no longer maintain a DeleteStore. DeleteSet is a temporary object that is created when needed. - When created in a transaction, it must only be accessed after sorting, and merging - This DeleteSet is sent to other clients - We do not create a DeleteSet when we send a sync message. The DeleteSet message is created directly from StructStore - We read a DeleteSet as part of a sync/update message. In this case the DeleteSet is already sorted and merged.
