InstanceStore.BeginExecute Method

Asynchronously executes persistence commands such as LoadWorkflowCommand and SaveWorkflowCommand.

Namespace:  System.Runtime.DurableInstancing
Assembly:  System.Runtime.DurableInstancing (in System.Runtime.DurableInstancing.dll)

public IAsyncResult BeginExecute(
	InstanceHandle handle,
	InstancePersistenceCommand command,
	TimeSpan timeout,
	AsyncCallback callback,
	Object state
)

Parameters

handle
Type: System.Runtime.DurableInstancing.InstanceHandle
An instance handle.
command
Type: System.Runtime.DurableInstancing.InstancePersistenceCommand
The command to be executed.
timeout
Type: System.TimeSpan
The timeout value for the command execution.
callback
Type: System.AsyncCallback
The asynchronous callback delegate that receives notification of the completion of the asynchronous operation.
state
Type: System.Object
The state information.

Return Value

Type: System.IAsyncResult
The state of the asynchronous operation.

A host calls the BeginExecute(InstanceHandle, InstancePersistenceCommand, TimeSpan, AsyncCallback, Object) method to execute a persistence command against an instance handle asynchronously. The host obtains the instance handle by invoking the CreateInstanceHandle() method. The instance handle may be bound to entities that represent the context and subject of the command, such as an instance, instance owner, or instance lock. Only one command may be issued against an instance handle at a time.
