apple.coredata.NSConstraintConflict

All Implemented Interfaces:

NSObject

public class NSConstraintConflict
extends NSObject

Used to report merge conflicts which include uniqueness constraint violations. Optimistic locking failures will be reported separately from uniquness conflicts and will be resolved first. Each constraint violated will result in a separate NSMergeConflict, although if an entity hierarchy has a constraint which is extended in subentities, all constraint violations for that constraint will be collapsed into a single report.

conflictingObjects

public NSArray<? extends NSManagedObject> conflictingObjects()

The objects in violation of the constraint. May contain one (in the case of a db level conflict) or more objects.

conflictingSnapshots

public NSArray<? extends NSDictionary<?,?>> conflictingSnapshots()

The original property values of objects in violation of the constraint. Will contain as many objects as there are conflictingObjects. If an object was unchanged, its snapshot will instead be -[NSNull null].

constraint

public NSArray<java.lang.String> constraint()

The constraint which has been violated.

constraintValues

public NSDictionary<java.lang.String,?> constraintValues()

The values which the conflictingObjects had when this conflict was created. May no longer match the values of any conflicted object if something else resolved the conflict.

databaseObject

public NSManagedObject databaseObject()

Object whose DB row is using constraint values. May be null if this is a context-level violation.

databaseSnapshot

public NSDictionary<java.lang.String,?> databaseSnapshot()

DB row already using constraint values. May be null if this is a context-level violation.

init

public NSConstraintConflict init()

There are two situations in which a constraint conflict may occur:

1. Between multiple objects being saved in a single managed object context. In this case, the conflict will have a nil database object/snapshot, and multiple conflicting objects/snapshots representing the state of the objects when they were first faulted or inserted into the context.

2. Between a single object being saved in a managed object context and the external store. In this case, the constraint conflict will have a database object, the current row snapshot for the database object, plus a a single conflicting object and its snapshot from when it was first faulted or inserted.

Snapshot dictionaries include values for all attributes and to-one relationships, but not to-many relationships. Relationship values are NSManagedObjectID references. to-many relationships must be pulled from the persistent store as needed.
