ManualWorkflowSchedulerService Class

Provides a threading service that allows the host application creating a workflow instance to donate the Thread on which the workflow instance is run. Using this threading service, host applications can run a workflow instance on a single Thread in synchronous mode (although if the workflow contains a delay activity, the work is postponed until after the delay activity is executed on a separate thread spawned by [System.Threading.Timer]).This mode blocks the execution of the host application until the workflow instance becomes idle. Subsequently, the workflow instance can only be executed using the RunWorkflow method of this service.

public class ManualWorkflowSchedulerService : WorkflowSchedulerService

The ManualWorkflowSchedulerService type exposes the following members.

  NameDescription
Public methodManualWorkflowSchedulerService()Initializes a new instance of the ManualWorkflowSchedulerService class.

  NameDescription
Protected propertyRuntimeGets the WorkflowRuntime for this service. (Inherited from WorkflowRuntimeService.)
Protected propertyStateGets the state of the WorkflowRuntimeService. (Inherited from WorkflowRuntimeService.)
Top

  NameDescription
Protected methodCancelCancels the specified existing workflow instance work item. (Overrides WorkflowSchedulerService.Cancel(Guid).)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnStartedOverloaded from WorkflowRuntimeService.OnStarted. This method is called whenever WorkflowRuntime.StartRuntime is called and is used by the ManualWorkflowSchedulerService to do work that is needed when the WorkflowRuntime starts. (Overrides WorkflowRuntimeService.OnStarted().)
Protected methodOnStoppedWhen overridden in a derived class, represents the method that will be called when the workflow runtime engine raises the WorkflowRuntime.Stopped event. (Inherited from WorkflowRuntimeService.)
Protected methodRaiseServicesExceptionNotHandledEventRaises the WorkflowRuntime.ServicesExceptionNotHandled event. (Inherited from WorkflowRuntimeService.)
Public methodRunWorkflowRuns the specified workflow instance.
Protected methodSchedule(WaitCallback, Guid)Adds a workflow instance to the pending work items queue using the specified workflow instance using the specified multicast delegate. (Overrides WorkflowSchedulerService.Schedule(WaitCallback, Guid).)
Protected methodSchedule(WaitCallback, Guid, DateTime, Guid)Adds the specified workflow instance to the pending work item queue using the specified multicast delegate, DateTime and GUIDs. (Overrides WorkflowSchedulerService.Schedule(WaitCallback, Guid, DateTime, Guid).)
Protected methodStartWhen overridden in a derived class, starts the service and changes the State to Starting. (Inherited from WorkflowRuntimeService.)
Protected methodStopOverloaded from WorkflowRuntimeService.Stop. The ManualWorkflowSchedulerService uses this method to do work that is needed when the WorkflowRuntime stops. (Overrides WorkflowRuntimeService.Stop().)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

ManualWorkflowSchedulerService does not automatically run a workflow instance that is in the queue. The host must call RunWorkflow to run a specified workflow.
