Instance Method Details

- (Object) initWithObjectID(objectID, withValues:values, version:version)

Returns an object initialized with the given values.

Parameters:

  • objectID (NSManagedObjectID) —

    A managed object ID.

  • values (Hash) —

    A dictionary containing the values persisted in an external store with keys corresponding to the names of the property description in the NSEntityDescription object described by objectID:For attributes: an immutable value (an instance of a value class such as NSNumber, NSString, NSData). Missing attribute keys will assume a nil value.For to-one relationships: the managed object ID of the related object or an instance of NSNull for nil relationship values. A missing key will be resolved lazily through calling newValueForRelationship:forObjectWithID:withContext:error: on the NSPersistentStore object. Lazy resolution for to-one relationships is discouraged.For to-many relationships: an instance of NSArray or NSSet containing the managed object IDs of the related objects. Empty to-many relationships must be represented by an empty non-nil collection. A missing key will be resolved lazily through calling newValueForRelationship:forObjectWithID:withContext:error: on the NSPersistentStore object. Lazy resolution for to-many relationships is encouraged.Unknown or unmodeled keys are stripped out.

  • version (Integer) —

    The revision number of this state. This value is used for conflict detection and merging.

Returns:

  • (Object) —

    An object initialized with the given values.

- (NSManagedObjectID) objectID

Returns the object ID that identifies the data stored by the receiver.

Returns:

  • (NSManagedObjectID) —

    The object ID that identifies the data stored by the receiver.

- (Object) updateWithValues(values, version:version)

Update the values and version to reflect new data being saved to or loaded from the external store. Update the values and version to reflect new data being saved to or loaded from the external store. // The values dictionary is in the same format as the initializer

Parameters:

  • values (Hash) —

    A dictionary containing updated values, in the same format as that described in initWithObjectID:withValues:version:.

  • version (Integer) —

    The version number for the transaction.

Returns:

- (Object) valueForPropertyDescription(prop)

Returns the value for the given property. If a relationship is nil, you should create a new value by invoking newValueForRelationship:forObjectWithID:withContext:error: on the NSPersistentStore object.

Parameters:

Returns:

  • (Object) —

    The value for the property specified by prop. May return an instance of NSNull for to-one relationships.

- (Integer) version

Return the version of data in the receiver.

Returns:

  • (Integer) —

    The version of data in the receiver.
