Hi Keith,
your rewrite of MAChainAccessor provoked some panic
here!
sorry, I didn't expect that anybody was using those.
I think with the refactoring they became more useful, especially since
you don't need to know anymore about the details. You can now just write
aDescription accessor: #foo
and it will automatically create the appropriate accessor object for
you. The same for
aDescription accessor: #(foo bar)
will chain #foo to #bar.
Just to let you know that I had written a couple of
chaining and
unchaining operaterations, which I use for mapping a flat db query
into a magritte model. It allows me to treat a chain accessor as a
kind of stack as the model is traversed.
I don't know if that is useful in general? If you think so, please
feel free to add it to Magritte-Core. I saw that you use it to build a
stack. Wouldn't it be much simpler if you just kept the selectors in
an OrderedCollection and sent #asAccessor if required?
Cheers,
Lukas
