DBBatchUploadData

Objective-C

@interface DBBatchUploadData : NSObject

Swift

class DBBatchUploadData : NSObject

Stores data for a particular batch upload attempt.

  • The queue on which most response handling is performed.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSOperationQueue *_Nonnull queue;

    Swift

    var queue: OperationQueue { get }

  • The queue on which we sleep until all processing is completed or the timeout is hit.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSOperationQueue *_Nonnull pollingQueue;

    Swift

    var pollingQueue: OperationQueue { get }

  • The dispatch group that pairs upload requests with upload responses so that we can wait for all request/response pairs to complete before batch committing. In this way, we can start many upload requests (for files under the chunk limit), without waiting for the corresponding response.

    Declaration

    Objective-C

    @property (nonatomic, readonly) dispatch_group_t _Nonnull uploadGroup;

    Swift

    var uploadGroup: DispatchGroup { get }

  • A client-supplied parameter that maps the file urls of the files to upload to the corresponding commit info objects.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSDictionary<NSURL *, DBFILESCommitInfo *> *_Nonnull fileUrlsToCommitInfo;

    Swift

    var fileUrlsToCommitInfo: [URL : DBFILESCommitInfo] { get }

  • Mapping of urls for files that were unsuccessfully uploaded to any request errors that were encounted.

    Declaration

    Objective-C

    @property (readonly) NSMutableDictionary<NSURL *, DBRequestError *> *_Nonnull fileUrlsToRequestErrors;

    Swift

    var fileUrlsToRequestErrors: NSMutableDictionary { get }

  • List of finish args (which include commit info, cursor, etc.) which the SDK maintains and passes to upload_session/finish_batch.

    Declaration

    Objective-C

    @property (strong) NSMutableArray<DBFILESUploadSessionFinishArg *> *_Nonnull finishArgs;

    Swift

    var finishArgs: NSMutableArray { get set }

  • The progress block that is periodically executed once a file upload is complete.

    Declaration

    Objective-C

    @property (nonatomic, readonly) DBProgressBlock _Nullable progressBlock;

    Swift

    var progressBlock: DBProgressBlock? { get }

  • The response block that is executed once all file uploads and the final batch commit is complete.

    Declaration

    Objective-C

    @property (nonatomic, readonly) DBBatchUploadResponseBlock _Nonnull responseBlock;

    Swift

    var responseBlock: DBBatchUploadResponseBlock { get }

  • The total size of all the files to upload. Used to return progress data to the client.

    Declaration

    Objective-C

    @property (nonatomic) NSUInteger totalUploadSize;

    Swift

    var totalUploadSize: UInt { get set }

  • The total size of all the file content upload so far. Used to return progress data to the client.

    Declaration

    Objective-C

    @property (nonatomic) NSUInteger totalUploadedSoFar;

    Swift

    var totalUploadedSoFar: UInt { get set }

  • The flag that determines whether upload continues or not.

    Declaration

    Objective-C

    @property BOOL cancel;

    Swift

    var cancel: Bool { get set }

  • The container object that stores all upload / download task objects for cancelling.

    Declaration

    Objective-C

    @property (nonatomic, strong) DBTasksStorage *_Nonnull taskStorage;

    Swift

    var taskStorage: DBTasksStorage { get set }

  • Full constructor.

    Declaration

    Objective-C

    - (nonnull instancetype)
    initWithFileCommitInfo:
        (nonnull NSDictionary<NSURL *, DBFILESCommitInfo *> *)
            fileUrlsToCommitInfo

             responseBlock:(nonnull DBBatchUploadResponseBlock)responseBlock
                     queue:(nonnull NSOperationQueue *)queue;

    Swift

    init(fileCommitInfo fileUrlsToCommitInfo: [URL : DBFILESCommitInfo], progressBlock: DBProgressBlock?, responseBlock: @escaping DBBatchUploadResponseBlock, queue: OperationQueue)
