SyncStreamObserver

Observer for all operations on a SyncStream. You should create your own subclass of StreamObserver and override functions you are interested in. Observer will receive callbacks for all operations on a SyncStream. 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.
