| Conforms to | NSObject |
| Declared in | RKManagedObjectCaching.h |
Overview
Objects implementing the RKManagedObjectCaching provide support for retrieving managed object matching a set of attributes using an opaque caching strategy. The objects retrieved are not required to be in any particular order, but must exactly match the attribute values requested.
Tasks

-
– managedObjectsWithEntity:attributeValues:inManagedObjectContext:Returns all managed objects for a given entity with attributes whose names and values match the given dictionary in a given context.
required method -

– didCreateObject:Invoked to inform the receiver that an object was created and should be added to the cache.
-
– didDeleteObject:Invoked to inform the receiver that an object was deleted and should be removed to the cache.
