DBASYNCPollEmptyResult

@interface DBASYNCPollEmptyResult : NSObject <DBSerializable, NSCopying>

The PollEmptyResult union.

Result returned by methods that poll for the status of an asynchronous job. Upon completion of the job, no additional information is returned.

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

  • Initializes union class with tag state of in_progress.

    Description of the in_progress tag state: The asynchronous job is still in progress.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithInProgress;

    Swift

    init(inProgress: ())

    Return Value

    An initialized instance.

  • Initializes union class with tag state of complete.

    Description of the complete tag state: The asynchronous job has completed successfully.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithComplete;

    Swift

    init(complete: ())

    Return Value

    An initialized instance.

  • Retrieves whether the union’s current tag state has value in_progress.

    Declaration

    Objective-C

    - (BOOL)isInProgress;

    Swift

    func isInProgress() -> Bool

    Return Value

    Whether the union’s current tag state has value in_progress.

  • Retrieves whether the union’s current tag state has value complete.

    Declaration

    Objective-C

    - (BOOL)isComplete;

    Swift

    func isComplete() -> Bool

    Return Value

    Whether the union’s current tag state has value complete.

  • Retrieves string value of union’s current tag state.

    Declaration

    Objective-C

    - (nonnull NSString *)tagName;

    Swift

    func tagName() -> String

    Return Value

    A human-readable string representing the union’s current tag state.
