## Discussion

All the receiver’s managed objects are “forgotten.” If you use this method, you should ensure that you also discard references to any managed objects fetched using the receiver, since they will be invalid afterwards.

## See Also

[`stalenessInterval`](/documentation/CoreData/NSManagedObjectContext/stalenessInterval)

The maximum length of time that may have elapsed since the store previously fetched data before fulfilling a fault issues a new fetch.
