public void ChangeModel( 
   ModelChangedEventArgs e,
   bool undo
)

Parameters

e

an edit describing the change to be performed

undo

true if undoing; false if redoing

When e's ModelChangedEventArgs.Change value is ModelChange.Property, this calls ChangeModelValue if the ModelChangedEventArgs.Data is this model, or else it calls ChangeDataValue.

This method handles all other ModelChange cases, since they are all predefined.
