1) Can CoreData properly manage an object graph where the objects form a circular reference (i.e.)
Entity Node
int nodeType
Node onTopOf // 1:1 relationship to another Node entity
Node under // another 1:1 relationship
End
This would be a doubly-linked list in a circular queue so that you could go either direction from any Node entity. My guess is… no.
2) Without CoreData, if I simply declare in my model classes that they implement <NSCoding> (and I implement all the initWithCoder: and encodeWithCoder: methods), will this properly handle such a situation (i.e. a possibly circular object graph)?
