DBFILESThumbnailV2Error

Objective-C

@interface DBFILESThumbnailV2Error : NSObject <DBSerializable, NSCopying>

Swift

class DBFILESThumbnailV2Error : NSObject, DBSerializable, NSCopying

The ThumbnailV2Error union.

This class implements the DBSerializable protocol (serialize and deserialize instance methods), which is required for all Obj-C SDK API route objects.

Instance fields

  • tag

    Represents the union’s current tag state.

    Declaration

    Objective-C

    @property (nonatomic, readonly) DBFILESThumbnailV2ErrorTag tag;

    Swift

    var tag: DBFILESThumbnailV2ErrorTag { get }

  • An error occurred when downloading metadata for the image. - note: Ensure the isPath method returns true before accessing, otherwise a runtime exception will be raised.

    Declaration

    Objective-C

    @property (nonatomic, readonly) DBFILESLookupError *_Nonnull path;

    Swift

    var path: DBFILESLookupError { get }
