This method gets the intermediate model passed, which the NodeModel passes to the notifyViews method, i.e. these methods have to correspond. The updatePaintModel method is assumed to know how to visualize the intermediate view model. 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)
