[cdt-dev] MBS - Questions to Options and OptionCategories

[Lars.Kurth@xxxxxxxxxxx]

Hi Leo,
I have a question regarding Options
and OptionCategories which is caused by the implementation work for the
Shared Tool Options proposal. The proposal would allow Options and OptionCategories
to be children of ITool and of IToolChain, depending on what is defined
in .buildDefinitions.    
Now this means that we have to cater
for the fact that the "parent" of these may either be ITool or
IToolchain. Currently

• IOptions defines "ITool getParent()" and
• IOptionCategory defines "ITool getTool()"

I have essentially
two choices to handle the interface: either I use getTool() and getToolChain()
for both interfaces, where the invalid one returns null. Or I use "Object
getParent()" and return the appropriate object. 
Do you have any preferences? Note that
I prefer the first approach. Also if I went for the first approach, would
you be happy if I renamed IOptions::getParent() to getTool().
Best Regards
-- Lars
