Hi, I get the possible bug 'Overrides super method without calling it' for things like:
Strand>>size ^ genes size
I can't find an explanation of this, in case there is some nasty that I'm not aware of. It is not listed at:
http://st-www.cs.uiuc.edu/users/brant/Refactory/LintChecks.html
Is there a more complete list of code critics messages?
Are there cases other than 'Overrides a "special" message' to look out for?
Thanks, ...Stan
Hi,
The idea is that you should _maybe_ give the superclasses of Strand a chance to execute their method. In some situations this is really necessary, or just a good way to avoid code duplication.

Thanks Matthias.
I just worked out that to allow Strand to call super size, it needs to implement
isVariable ^ true
This doesn't do anything useful, but it does get code critics off my back (until I implement Lukas's revised code critics package).
I was concerned that there might be less obvious repercussions, such as the one at: http://st-www.cs.uiuc.edu/users/brant/Refactory/LintChecks.html
"Has class instance variable but no initialize method
Checks that all classes that have class instance variables also have an initialize method. This makes sure that all class instance variables are initialized properly when the class is filed-into a new image. "
I hadn't thought about the file in implications; similarly I didn't know if there were any unseen nasties in the 'Overrides super method without calling it' case.
