Instance Attribute Details
- (Hash) cachedSnapshot (readonly)
A dictionary containing the values of the source object held in the persistent store coordinator layer. (read-only)
- (Integer) newVersionNumber (readonly)
The new version number for the change. (read-only) A new version number of 0 means the object was deleted and the corresponding snapshot is nil.
- (Hash) objectSnapshot (readonly)
A dictionary containing the values of the source object. (read-only)
- (Integer) oldVersionNumber (readonly)
The old version number for the change. (read-only)
- (Hash) persistedSnapshot (readonly)
A dictionary containing the values of the source object held in the persistent store. (read-only)
- (NSManagedObject) sourceObject (readonly)
The source object for the conflict. (read-only)
Instance Method Details
- (Object) initWithSource(srcObject, newVersion:newvers, oldVersion:oldvers, cachedSnapshot:cachesnap, persistedSnapshot:persnap)
Initializes a merge conflict.
