COItemGraph class documentationCOItemGraph <NSObject>
All objects must have a composite or non-composite relationship path to the root (garbage-collected graph approach). This can be violated in the short term while making a batch of changes.
Garbage collection is not covered by this protocol.
- - (COItem *) itemForUUID: (ETUUID *)aUUID
Returns an immutable item for the UUID.
- - (NSArray *) itemUUIDs
Returns all the item UUIDs in the graph, including -rootItemUUID .
