public class NSDerivedAttributeDescription
extends NSAttributeDescription

Class that describes an attribute whose value should be derived from one or more other properties and how that derivation should be done. This is primarily intended to optimize fetch performance. Some use cases: * creating a derived 'searchName' attribute that reflects a 'name' attribute with case and diacritics stripped for more efficient comparisons during fetching * creating a 'relationshipCount' attribute reflecting the number of objects in a relationship and so avoid having to do a join during fetching IMPORTANT: Derived attributes will be recomputed during save, recomputed values will not be reflected in a managed object's property until after a save. NOTE: Prior to macOS 10.16, iOS 14.0, tvOS 14.0, and watchOS 7.0 a refresh of the object is required after a save to reflect recomputed values

derivationExpression

public NSExpression derivationExpression()

Instance of NSExpression that will be used to generate the derived data.
