Classes

The following classes are available globally.

CBLArray
CBLArray provides read access to array data.

Declaration
Objective-C

@interface CBLArray : NSObject <CBLArray, NSCopying, NSMutableCopying>
CBLAuthenticator
Authenticator objects provide server authentication credentials to the replicator. CBLAuthenticator is an abstract superclass; you must instantiate one of its subclasses. CBLAuthenticator is not meant to be subclassed by applications.
See more
Declaration
Objective-C

@interface CBLAuthenticator : NSObject
CBLBasicAuthenticator
The CBLBasicAuthenticator class is an authenticator that will authenticate using HTTP Basic auth with the given username and password. This should only be used over an SSL/TLS connection, as otherwise it’s very easy for anyone sniffing network traffic to read the password.
See more
Declaration
Objective-C

@interface CBLBasicAuthenticator : CBLAuthenticator
CBLBlob
A CBLBlob contains arbitrary binary data, tagged with a MIME type. Blobs can be arbitrarily large, and their data is loaded only on demand (when the content or contentStream properties are accessed), not when the document is loaded. The document’s raw JSON form only contains the CBLBlob’s metadata (type, length and a digest of the data) in a small object. The data itself is stored externally to the document, keyed by the digest.

Declaration
Objective-C

@interface CBLBlob : NSObject
CBLClientCertificateAuthenticator
ENTERPRISE EDITION ONLY.

An authenticator that presents a client certificate to the server during the initial SSL/TLS handshake. This is currently used for authenticating with CBLURLEndpointListener only.
See more
Declaration
Objective-C

@interface CBLClientCertificateAuthenticator : CBLAuthenticator
CBLCollection
A CBLCollection represent a collection which is a container for documents.

A collection can be thought as a table in the relational database. Each collection belongs to a scope which is simply a namespace, and has a name which is unique within its scope.

When a new database is created, a default collection named “_default” will be automatically created. The default collection is created under the default scope named “_default”. The name of the default collection and scope can be referenced by using kCBLDefaultCollectionName and kCBLDefaultScopeName constant.

Note
The default collection cannot be deleted.

When creating a new collection, the collection name, and the scope name are required. The naming rules of the collections and scopes are as follows:
- Must be between 1 and 251 characters in length.
- Can only contain the characters A-Z, a-z, 0-9, and the symbols _, -, and %.
- Cannot start with _ or %.
- Both scope and collection names are case sensitive.
CBLCollection Lifespan

A Collection object and its reference remain valid until either the database is closed or the collection itself is deleted, in that case it will return CBLErrorNotOpen while accessing the collection APIs.

Legacy Database and API

When using the legacy database, the existing documents and indexes in the database will be automatically migrated to the default collection.

Any pre-existing database functions that refer to documents, listeners, and indexes without specifying a collection such as \ref [database documentWithID:]] will implicitly operate on the default collection. In other words, they behave exactly the way they used to, but collection-aware code should avoid them and use the new Collection API instead. These legacy functions are deprecated and will be removed eventually.

CBLCoreMLPredictiveModel
ENTERPRISE EDITION ONLY

CBLCoreMLPredictiveModel is a Core ML based implementation of the CBLPredictiveModel protocol. Basically the CBLCoreMLPredictiveModel used a Core ML model to return prediction results.

CBLCoreMLPredictiveModel automatically converts between Couchbase Lite data and Core ML data when calling into the MLModel object to return prediction results. All Core ML data types including Int64, Double, String, Dictionary, MultiArray, Image, and Sequence are supported.

When the MLObject has a single input and the input type is Image, CBLCoreMLPredictiveModel will use Vision framework via the VNCoreMLModel to process the input image and call into the MLModel object. The CBLCoreMLPredictiveModel supports all VNObservation types including VNClassificationObservation, VNCoreMLFeatureValueObservation, and VNPixelBufferObservation as mentioned in https://developer.apple.com/documentation/vision/vncoremlrequest.

However there is a compatibility limitation when the VNCoreMLModel returns VNCoreMLFeatureValueObservation or VNPixelBufferObservation results that the MLModel must return a single output, otherwise the observation outputs cannot be mapped to the MLModel outputs. When the VNCoreMLModel cannot be used to result the prediction result, CoreMLPredictiveModel will fall back to use the MLModel instead.

When converting from blob data to VNPixelBuffer for an input image, only ARGB pixel format is currently supported. However this limitation is applied only when the VNCoreMLModel cannot be used.

A key used for accessing the projecting result value could be one of the followings:
- The alias name of the CBLQuerySelectResult object.
- The last component of the keypath or property name of the property expression used when creating the CBLQuerySelectResult object.
- The provision key in $1, $2, …$N format for the CBLQuerySelectResult that doesn’t have an alias name specified or is not a property expression such as an aggregate function expression (e.g. count(), avg(), min(), max(), sum() and etc).
