Detailed Description

Observer for all operations on a Document.

You should create your own subclass of DocumentObserver and override functions you are interested in.

Observer will receive callbacks for all operations on a Document. To distinguish parallel streams of local operations your application could use local flow identifier.

Callbacks in the observer will be called from a background thread. You will need to repost your work to UI thread if you do any UI-related operations in the callback.
