Is it possible to somehow set immutable superclass properties in a subclass constructor? It seems not, but maybe I'm just misinterpreting the documentation and error messages and this is possible somehow?
In case this doesn't make sense, my motivation is this: I've written a fairly nice data-analysis object that I use as a superclass all the time. It loads data from the data acquisition tool we normally use, and I have different subclasses for different experiments, which have different analysis requirements but most of the basics are the same (and located in the superclass).
Now I'd like to re-use all that code by loading data (of essentially the same form) but from a different filetype (new constructor required) into the properties expected by the superclass. I could just make the properties protected in the superclass (instead of immutable), but I'd really like them to only be changed within the constructor of the new subclass.
Or maybe I should be approaching this in a different way entirely?
