    + (nonnull CBLQueryExpression *)contains:
                                    (nonnull CBLQueryExpression *)expression
                                   value:(nonnull CBLQueryExpression *)value;

    Swift

    class func contains(_ expression: CBLQueryExpression, value: CBLQueryExpression) -> CBLQueryExpression

    Parameters

    expression

    Objective-C

    + (nonnull CBLQueryExpression *)length:(nonnull CBLQueryExpression *)expression;

    Swift

    class func length(_ expression: CBLQueryExpression) -> CBLQueryExpression

    Parameters

    expression
