RKManagedObjectCacheing Protocol Reference
| Declared in | RKManagedObjectMappingCache.h |
Overview
Objects implementing the RKManagedObjectCacheing protocol can act as the cache strategy for RestKit managed object stores. The managed object cache is consulted when objects are retrieved from Core Data during object mapping operations and provide an opportunity to accelerate the mapping process by trading memory for speed.
