TimerEventSubscriptionCollection Class
Represents an ordered list of TimerEventSubscription objects.
Assembly: System.Workflow.Runtime (in System.Workflow.Runtime.dll)
The TimerEventSubscriptionCollection type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | Count | Gets the number of TimerEventSubscription objects in the timer queue. |
![]() | IsSynchronized | Gets a value that indicates whether the access to the TimerEventSubscriptionCollection is synchronized (thread safe). |
![]() | SyncRoot | Gets an object that can be used to synchronize access to the TimerEventSubscriptionCollection. |
| Name | Description | |
|---|---|---|
![]() | Add | Adds a TimerEventSubscription to the timer queue. |
![]() | CopyTo | Copies the TimerEventSubscriptionCollection elements to an existing one-dimensional Array, starting at the specified array index. |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetEnumerator | Returns an enumerator that iterates through the TimerEventSubscriptionCollection. |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | Peek | Returns the TimerEventSubscription at the beginning of the timer queue without removing it. |
![]() | Remove(Guid) | Removes the TimerEventSubscription that has the specified subscription id from the timer queue. |
![]() | Remove(TimerEventSubscription) | Removes the TimerEventSubscription from the timer queue. |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() | AsParallel | Enables parallelization of a query. (Defined by ParallelEnumerable.) |
![]() | AsQueryable | Converts an IEnumerable to an IQueryable. (Defined by Queryable.) |
![]() | Cast<TResult> | Converts the elements of an IEnumerable to the specified type. (Defined by Enumerable.) |
![]() | OfType<TResult> | Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.) |
| Name | Description | |
|---|---|---|
![]() ![]() | TimerCollectionProperty | Timer queue associated with a workflow instance. This queue contains time ordered TimerEventSubscription objects for a workflow. |
A TimerEventSubscriptionCollection represents the queue of TimerEventSubscription objects associated with a workflow instance and provides methods to manage this queue. Subscriptions are ordered in the queue based on their ExpiresAt values; those with smaller ExpiresAt values are positioned before those with larger ExpiresAt values. You can use the methods provided by this class to manage the collection of active timer event subscriptions exposed by TimerCollectionProperty for each workflow instance. You can use Add or Remove to add or remove subscriptions from the timer queue. Whenever the first element in the timer queue changes, the WorkflowSchedulerService is called to cancel the timer event that was previously at the beginning of the queue and schedule the new timer event.
