[Cuis-dev] Do classes know what package they come from ?

[Gerald Klix]

I am inclined to say "no' here ;-}

The package of a class is determined by its category,
to be precise the packages now which classes they
are responsible for.

Please see Object class>>#package and
follow the chain of implementers.
You will end at CodePackage>>#includesClass:

It is possible to subclass CodePackage for
your package and do something entirely different
here, up to messing things up beyond repair.

For your purpose `MySpiffyClass package fullFileName`
should be sufficient.


HTH,

Gerald
