The difference is that people can export from outside a CustomSourceLanguage with a string representing the language, while the UnknownSourceLanguage is provided by default (null object pattern).

So, the CustomSourceLanguage is simply a possibility to still specify some strange language from an outside parser without requiring a change in the Smalltalk code. For example, when you implemented the C# parser, you could export the language information even if we did not modify the Smalltalk code.

What is the different between objects represented by FamixUnknownSourceLanguage and FamixCustomSourceLanguage? Do we have an example to show the difference? thanx Usman and Nicolas _______________________________________________ Moose-dev mailing list Moose-dev@iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
