)

Parameters

store (NSPersistentStore): A persistent store.

URL (NSURL): An URL object that specifies the location for the new store.

options (NSDictionary): A dictionary containing key-value pairs that specify whether the store should be read-only, and whether (for an XML store) the XML file should be validated against the DTD before it is read. For key definitions, see “Store Options.”

storeType (NSString): A string constant (such as NSSQLiteStoreType) that specifies the type of the new store—see “Store Types.”

error (NSError%): If an error occurs, upon return contains an instance of NSError that describes the problem.

Return Value
