The focus of the article is not on the source code, but on building a visual modelling language and framework code for a specific, narrow domain. The best way to investigate how this works is to download MetaEdit+ from www.metacase.com, and look at the Watch Example. This contains the domain-specific modelling language, code generators, and models from which the code here was generated.
