This method can be called from the derived model in order to inform the views about changes of the settings or during execution, if you want the views to show the progress, and if they can display models half way through the execution. In the view NodeView#updateModel(Object) is called and needs to be overridden. Usually, the NodeView displays the data when the NodeModel has finished execution. There is also a possibility to watch how the model is generated to update the view during execution of the NodeModel. This built-in functionality of KNIME can be used with these three methods:

  1. NodeModel#notifyViews(Object)
  2. NodeView#setNODATALabel(false)
  3. NodeView#updatePaintModel(Object)
