AmplifyInProcessReportingOperation

open class AmplifyInProcessReportingOperation<
    Request: AmplifyOperationRequest,
    InProcess,
    Success,
    Failure: AmplifyError
>: AmplifyOperation<Request, Success, Failure>

An AmplifyOperation that emits InProcess values intermittently during the operation.

Unlike a regular AmplifyOperation, which emits a single Result at the completion of the operation’s work, an AmplifyInProcessReportingOperation may emit intermediate values while its work is ongoing. These values could be incidental to the operation (such as a Storage.downloadFile operation reporting Progress values periodically as the download proceeds), or they could be the primary delivery mechanism for an operation (such as a GraphQLSubscriptionOperation‘s emitting new subscription values).

InProcess
Declaration
Swift

public typealias InProcess = InProcess


                    
                    
                    init(categoryType:eventName:request:inProcessListener:resultListener:)

Declaration

Swift

public init(categoryType: CategoryType,
            eventName: HubPayloadEventName,
            request: Request,
            inProcessListener: InProcessListener? = nil,
            resultListener: ResultListener? = nil)

cancel()
Classes that override this method must emit a completion to the inProcessPublisher upon cancellation
Declaration
Swift

open override func cancel()


                    
                    
                    dispatch(result:)

Invokes super.dispatch(). On iOS 13+, this method first publishes a .finished completion on the in-process publisher.

Declaration

Swift

public override func dispatch(result: OperationResult)

Parameters


                                result

The OperationResult to dispatch to the hub as part of the HubPayload

InProcessListener
Convenience typealias for the inProcessListener callback submitted during Operation creation
Declaration
Swift

typealias InProcessListener = (InProcess) -> Void


                    
                    
                    dispatchInProcess(data:)

Dispatches an event to the hub. Internally, creates an AmplifyOperationContext object from the operation’s id, and request

Declaration

Swift

func dispatchInProcess(data: InProcess)

Parameters


                                result

The OperationResult to dispatch to the hub as part of the HubPayload

removeInProcessResultListener()
Removes the listener that was registered during operation instantiation
Declaration
Swift

func removeInProcessResultListener()


                    
                    
                    inProcessPublisher

Publishes in-process updates

Declaration

Swift

var inProcessPublisher: AnyPublisher<InProcess, Never> { get }
