For reasons which will become a bit clearer after April 29, I am
implementing a linked list which I want to control with an
NSArrayController. The most obvious way of doing this is simply to
bind the content of the array controller to a method which gets and
sets the linked list as an NSArray. But I wonder if there are subtler
and better ways of doing it? Is NSArrayController's only interaction
with its content object via the accessor or are there methods I could
implement which it would use? Obviously it would be more efficient
for me to implement addObject than for the controller to add it to an
array, and then me set the entire linked list using the array.
