LockingPersistenceProvider.BeginLoad Method

Definition

Namespace:

System.ServiceModel.Persistence

Assembly:

System.WorkflowServices.dll

Begins an asynchronous operation to load an instance based on state information in the persistence store.

Overloads

BeginLoad(TimeSpan, AsyncCallback, Object)	Begins an asynchronous operation to load an instance based on state information in the persistence store using the parameters. This method does not lock the instance.
BeginLoad(TimeSpan, Boolean, AsyncCallback, Object)	Begins an asynchronous operation to load an instance based on state information in the persistence store using the parameters. This method locks the instance after loading the instance state if the value of the lockInstance parameter is true.

BeginLoad(TimeSpan, AsyncCallback, Object)

Begins an asynchronous operation to load an instance based on state information in the persistence store using the parameters. This method does not lock the instance.

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

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

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

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

Parameters

timeout

TimeSpan

The interval in which the operation must be completed without timing out.

callback

AsyncCallback

The delegate that receives the notification when the operation completes.

state

Object

The state information associated with the asynchronous operation.

Returns

IAsyncResult

The status of an asynchronous operation.

Remarks

This method calls into the BeginLoad, which takes an additional parameter that specifies whether the instance must be locked in the persistence store. This method passes false as a value for this parameter to the calling method.

BeginLoad(TimeSpan, Boolean, AsyncCallback, Object)

Begins an asynchronous operation to load an instance based on state information in the persistence store using the parameters. This method locks the instance after loading the instance state if the value of the lockInstance parameter is true.

public:
 abstract IAsyncResult ^ BeginLoad(TimeSpan timeout, bool lockInstance, AsyncCallback ^ callback, System::Object ^ state);

public abstract IAsyncResult BeginLoad (TimeSpan timeout, bool lockInstance, AsyncCallback callback, object state);

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

Public MustOverride Function BeginLoad (timeout As TimeSpan, lockInstance As Boolean, callback As AsyncCallback, state As Object) As IAsyncResult

Parameters

timeout

TimeSpan

An interval in which the operation must be completed before timing out.

lockInstance

Boolean

true if the instance must be locked; otherwise false.

callback

AsyncCallback

The delegate that receives the notification when the operation completes.

state

Object

The state information associated with the asynchronous operation.

Returns

IAsyncResult

The status of an asynchronous operation.
