Hi,
I can't answer your first question, but concerning your second one:
check out NSPropertyDescription isTransient:. However, this applies to
properties, not entities. I don't think entities can be transient in
the true meaning of the word. But if all properties of an entity are
transient, it probably has the same effect.
Best,
Sebastian

Hey,
I am creating a server in which I would like to somehow add a
relationship
to an NSDistantObject in my Core Data object graph. I know
NSDistantObjects
can't be archived. I will have an an array of all of the live
NSDistantObjects in my application, I just need to relate them to
entities
in Core Data. Perhaps NSDistantObject instances have a unique
identifier I
can store in the data graph and use as a key to retrieve the live
instance?
For this I have considered the hash function or using the actual
pointer
value. However, I am not sure if either are very safe.
On a related note, I obviously wouldn't want these references to
NSDistantObjects to be saved to the persistent store. Is there a way
to mark
an entity in Core Data as temporary so they are not saved or restored?
Thank You,
Bridger Maxwell
