Method Documentation

getStorage:

- (nullable NCKeyValueStorage *) getStorage:

(nonnull NSString *)

name

Returns a handle to a storage by name, creating it if it does not exist.

Parameters

name	Storage name (case-sensitive).

Returns

Key–value storage instance KeyValueStorage

Swift code snippet:

        // Get or create different storage instances
        userStorage = storageManager.getStorage(name: "user_preferences")
        appStorage = storageManager.getStorage(name: "app_settings")
        cacheStorage = storageManager.getStorage(name: "cache")

Objective C code snippet:

    // Get or create different storage instances
    self.userStorage = [self.storageManager getStorage:@"user_preferences"];
    self.appStorage = [self.storageManager getStorage:@"app_settings"];
    self.cacheStorage = [self.storageManager getStorage:@"cache"];

getStorageList

- (nonnull NSArray< NSString * > *) getStorageList

Returns the list of all existing user storages.

Returns

List of storage names (implementation currently returns them in alphabetical order).

Swift code snippet:

        // Get list of all existing storages
        let storageList: [String] = storageManager.getStorageList()
        print("Existing storages: \‍(storageList)")

Objective C code snippet:

    // Get list of all existing storages
    NSArray<NSString *> *storageList = [self.storageManager getStorageList];
    NSLog(@"Existing storages: %@", storageList);

removeStorage:

- (void) removeStorage:

(nonnull NSString *)

name

Removes the storage and all its persisted data. If the storage does not exist, this is a no-op.

Parameters

name	Storage name (case-sensitive).

Existing handles to this storage become invalid after removal and further operations may fail.

Swift code snippet:

        // Remove storage and all its data
        storageManager.removeStorage(name: "test_storage")
        print("Removed test storage")

Objective C code snippet:

    // Remove storage and all its data
    [self.storageManager removeStorage:@"test_storage"];
    NSLog(@"Removed test storage");
