LockingPersistenceProvider.BeginUpdate Method

Definition

Namespace:

System.ServiceModel.Persistence

Assembly:

System.WorkflowServices.dll

Begins an asynchronous operation to update instance state information in the persistence store.

Overloads

BeginUpdate(Object, TimeSpan, Boolean, AsyncCallback, Object)	Begins an asynchronous operation to update instance state information in the persistence store using the parameters passed. This operation locks the instance in the persistence store if the value of the unlockInstance parameter is true.
BeginUpdate(Object, TimeSpan, AsyncCallback, Object)	Begins an asynchronous operation to update instance state information in the persistence store using the parameters passed. This operation does not unlock the instance in the instance store.

BeginUpdate(Object, TimeSpan, Boolean, AsyncCallback, Object)

Begins an asynchronous operation to update instance state information in the persistence store using the parameters passed. This operation locks the instance in the persistence store if the value of the unlockInstance parameter is true.

public:
 abstract IAsyncResult ^ BeginUpdate(System::Object ^ instance, TimeSpan timeout, bool unlockInstance, AsyncCallback ^ callback, System::Object ^ state);

public abstract IAsyncResult BeginUpdate (object instance, TimeSpan timeout, bool unlockInstance, AsyncCallback callback, object state);

override this.BeginUpdate : obj * TimeSpan * bool * AsyncCallback * obj -> IAsyncResult

Public MustOverride Function BeginUpdate (instance As Object, timeout As TimeSpan, unlockInstance As Boolean, callback As AsyncCallback, state As Object) As IAsyncResult

Parameters

instance

Object

The instance whose state information is being updated in the persistence store.

timeout

TimeSpan

The interval in which the operation must complete without timing out.

unlockInstance

Boolean

true if the instance must be locked after the instance state is updated in the persistence store; otherwise false.

callback

AsyncCallback

The delegate that receives the notification when the operation completes.

state

Object

The state information about the asynchronous operation.

Returns

IAsyncResult

The status of an asynchronous operation.

BeginUpdate(Object, TimeSpan, AsyncCallback, Object)

Begins an asynchronous operation to update instance state information in the persistence store using the parameters passed. This operation does not unlock the instance in the instance store.

public:
 override IAsyncResult ^ BeginUpdate(System::Object ^ instance, TimeSpan timeout, AsyncCallback ^ callback, System::Object ^ state);

public override IAsyncResult BeginUpdate (object instance, TimeSpan timeout, AsyncCallback callback, object state);

override this.BeginUpdate : obj * TimeSpan * AsyncCallback * obj -> IAsyncResult

Public Overrides Function BeginUpdate (instance As Object, timeout As TimeSpan, callback As AsyncCallback, state As Object) As IAsyncResult

Parameters

instance

Object

The instance whose state information is being updated in the persistence store.

timeout

TimeSpan

The interval in which the operation must complete without timing out.

callback

AsyncCallback

The delegate that receives the notification when the operation is completed.

state

Object

The state information about the asynchronous operation.

Returns

IAsyncResult

The status of an asynchronous operation.

Remarks

This method calls into the BeginUpdate method and passes a false value for the unlockInstance parameter.
