Hello List,
As I understand, when using NSAtomicStore, there is only a "load"
method to load the data. It looks like it is an "all or nothing"
operation.
However, if I want to load data from a server through some kind of
HTTP/XML/Whatever method and only receive a subset of data. How would
I implement this? For example, I want to retrieve a list of patients
from a hospital system. Obviously, I am not going to load all the
patients of the hospital!
Now, I can imagine having some king of global variable read by the
"load" method I implement to load only the list of patients I need.
But then, how is the faulting handled? A patient will refer to a list
of medications, a list of visits, etc... My load method, again, can't
deeply fetch all the objects potentially needed because I would end up
with all the objects in memory. So I suspect, if a fault is triggered
on an object in memory and the object is not (yet) in the local cache,
I need my NSAtomicStore (subclass) to be notified to read from my
distant store (HTTP/XML...) the missing object(s).
Is this possible currently?
Any thoughts or solutions for this problem are welcome!
Thanks,
Alexander
