The problem is that its not really a data structure problem. Its a
policy question (which then makes requirements of data structures). The
problems here are what to represent, when, and what the policies are in
regard to maintaining references, especially as the data is updated. It
also really don't matter so much what your object definition is, or the
range of types of references (which is really a policy decision as
well), its that you know you are going to have object references of
various forms, and once you have them, how do you manage storage in a
way that provides logical correctness.
Simple cases:
RootObject, which has several thousands of other objects descending
from it most of which are several generations down the tree, is
updated, changing the contents of a method and adding a new method
and attribute. What happens?
MagicObject which has the curious property of being able to be in
multiple locations and player inventories at the same time is
deleted from the system. What happens?
Other cases are fairly easy to extrapolate from the Given: above.
