PersistenceProvider::EndLoadIfChanged Method (IAsyncResult^, Object^%)

.NET Framework (current version)

Other Versions

When implemented in a derived class, represents the end of the LoadIfChanged phase. The LoadIfChanged phase occurs when state data is loaded into the persistence provider from the persistence store, and the state data in the persistence store has been changed.

Namespace: System.ServiceModel.Persistence
Assembly: System.WorkflowServices (in System.WorkflowServices.dll)

Syntax

C++

public:
virtual bool EndLoadIfChanged(
	IAsyncResult^ result,
	[OutAttribute] Object^% instance
)

Parameters

result: Type: System::IAsyncResult^
A reference to the result of the operation.

instance: Type: System::Object^%
The actual instance state.

Return Value

Type: System::Boolean

true if the instance out parameter has been set with the latest copy from the persistence store; false if the locally cached state is already up-to-date.

Examples

The following code demonstrates how to implement the EndLoadIfChanged method.

public override bool EndLoadIfChanged(IAsyncResult result, out object instance)
{
    base.ThrowIfDisposedOrNotOpen();
    instance = this.factory.EndLoad(result);
    return true;
}
