    • onDataChange

      void onDataChange(DataChangeEvent<T> event)
      Invoked when this listener receives a data change event from a data source to which it has been added.

      This event is fired when something has changed in the underlying data. It doesn't allow to distinguish different kind of events (add/remove/update). It means that the method implementation normally just reloads the whole data to refresh.

      Parameters:
      event - the received event, not null
