Constructors

iOSCallbackScheduler()

Declaration
protected iOSCallbackScheduler()

Fields

CALLBACK_NOTIFICATION_HORIZON_THRESHOLD

The callback notification horizon threshold. When using notifications to schedule the timing of callbacks, we must decide when the delay of a callback execution necessitates a notification rather than executing immediately. This is in part a practical question, in that executing a callback immediately rather than using a notification can improve performance -- imagine the app coming to the foreground and executing the callback right away versus deferring it to a future notification. This is also an iOS API consideration, as the iOS system will not schedule a notification if its fire date is in the past by the time it gets around to doing the scheduling. Whatever the value, it needs to be less than the DefaultPollingSleepDurationMS value.

Declaration
public static readonly TimeSpan CALLBACK_NOTIFICATION_HORIZON_THRESHOLD
Field Value
Type Description
System.TimeSpan

Properties

CallbackIds

Declaration
public abstract List<string> CallbackIds { get; }
Property Value
Type Description
System.Collections.Generic.List<System.String>

Methods

CancelSilentNotifications()

Cancels the silent notifications (e.g., those for health test) when the app is going into the background.

Declaration
public abstract void CancelSilentNotifications()

GetCallbackInfo(ScheduledCallback)

Declaration
public NSMutableDictionary GetCallbackInfo(ScheduledCallback callback)
Parameters
Type Name Description
ScheduledCallback callback
Returns
Type Description
Foundation.NSMutableDictionary

IsCallback(NSDictionary)

Declaration
public bool IsCallback(NSDictionary callbackInfo)
Parameters
Type Name Description
Foundation.NSDictionary callbackInfo
Returns
Type Description
System.Boolean

RaiseCallbackAsync(NSDictionary)

Declaration
public Task RaiseCallbackAsync(NSDictionary callbackInfo)
Parameters
Type Name Description
Foundation.NSDictionary callbackInfo
Returns
Type Description
System.Threading.Tasks.Task

RaiseCallbackAsync(ScheduledCallback, String)

Declaration
public override Task RaiseCallbackAsync(ScheduledCallback callback, string invocationId)
Parameters
Type Name Description
ScheduledCallback callback
System.String invocationId
Returns
Type Description
System.Threading.Tasks.Task
Overrides

ReissueSilentNotificationAsync(String)

Declaration
protected abstract Task ReissueSilentNotificationAsync(string id)
Parameters
Type Name Description
System.String id
Returns
Type Description
System.Threading.Tasks.Task

TryGetCallback(NSDictionary)

Declaration
public ScheduledCallback TryGetCallback(NSDictionary callbackInfo)
Parameters
Type Name Description
Foundation.NSDictionary callbackInfo
Returns
Type Description
ScheduledCallback

UpdateCallbacksOnActivationAsync()

Updates the callbacks when the app is activated. This services any callbacks that should have already been serviced or will be serviced in the near future. This also reissues all silent notifications, which would have been canceled when the app went into the background.

Declaration
public Task UpdateCallbacksOnActivationAsync()
Returns
Type Description
System.Threading.Tasks.Task

Async task.
