CBLCollectionConfiguration

@interface CBLCollectionConfiguration : NSObject

The collection configuration that can be configured specifically for the replication.

  • The custom conflict resolver function. If this value is nil, the default conflict resolver will be used.

    Declaration

    Objective-C

    @property (nonatomic, readonly) CBLCollection *_Nonnull collection;

  • The custom conflict resolver function. If this value is nil, the default conflict resolver will be used.

    Declaration

    Objective-C

    @property (nonatomic, nullable) id<CBLConflictResolver> conflictResolver;

  • Filter function for validating whether the documents can be pushed to the remote endpoint. Only documents of which the function returns true are replicated.

    Declaration

    Objective-C

    @property (nonatomic) int pushFilter;

  • Filter function for validating whether the documents can be pulled from the remote endpoint. Only documents of which the function returns true are replicated.

    Declaration

    Objective-C

    @property (nonatomic) int pullFilter;

  • Channels filter for specifying the channels for the pull the replicator will pull from. For any collections that do not have the channels filter specified, all accessible channels will be pulled. Push replicator will ignore this filter.

    @Note: Channels are not supported in Peer-to-Peer and Database-to-Database replication.

    Declaration

    Objective-C

    @property (nonatomic, nullable) NSArray<NSString *> *channels;

  • Document IDs filter to limit the documents in the collection to be replicated with the remote endpoint. If not specified, all docs in the collection will be replicated.

    Declaration

    Objective-C

    @property (nonatomic, nullable) NSArray<NSString *> *documentIDs;

  • Initializes a collection configuration with the given collection.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithCollection:(nonnull CBLCollection *)collection;

    Parameters

    collection

    The collection instance.

  • Creates an array of CBLCollectionConfiguration objects from the given collections.

    Each collection is wrapped in a CBLCollectionConfigurationusing default settings (no filters and no custom conflict resolvers).

    This is a convenience method for configuring multiple collections with default configurations.

    Declaration

    Objective-C

    + (nonnull NSArray<CBLCollectionConfiguration *> *)fromCollections:
    (nonnull NSArray<CBLCollection *> *)collections;

    Parameters

    collections

    The collections to replicate.

    Return Value

    An array of CBLCollectionConfiguration objects for the given collections.

  • Unavailable

    Not available

    Declaration

    Objective-C

    - (nonnull instancetype)init;
