SerializableObjectLayer Class

An object access layer used for units of work (or sessions) in distributed applications.

Namespace: DevExpress.Xpo

Assembly: DevExpress.Xpo.v24.1.dll

NuGet Packages: DevExpress.Win.PivotGrid, DevExpress.Win.TreeMap, DevExpress.Xpo

NuGet Package: DevExpress.Xpo

Declaration

C#

public class SerializableObjectLayer :
    ISerializableObjectLayer,
    ISerializableObjectLayerProvider,
    ISerializableObjectLayerEx,
    ICommandChannel,
    ICommandChannelAsync

VB.NET

Public Class SerializableObjectLayer
    Implements ISerializableObjectLayer,
               ISerializableObjectLayerProvider,
               ISerializableObjectLayerEx,
               ICommandChannel,
               ICommandChannelAsync

Remarks

The SerializableObjectLayer is a ready-to-use ISerializableObjectLayer implementation shipped with XPO. You can provide your own implementations and use them in your distributed applications.

Normally, a SerializableObjectLayer instance is provided via a proxy derived from the SerializableObjectLayerProxyBase to initialize a SerializableObjectLayerService-based service, as shown below.

C#

(ObjectWcfService.svc.cs)
public class ObjectService: SerializableObjectLayerService {
    // Initializing a service with a proxy providing a SerializableObjectLayer instance.
    public ObjectService(): base(new ObjectServiceProxy()) { 
    }

    static ObjectService() {
        // Initializing a data access layer (DAL).
        // ...
    }
}

public class ObjectServiceProxy: SerializableObjectLayerProxyBase {
    protected override SerializableObjectLayer GetObjectLayer() {
        return new SerializableObjectLayer(new UnitOfWork(), true);
    }
}

VB.NET

(ObjectWcfService.svc.vb)
Public Class ObjectService
    Inherits SerializableObjectLayerService
    ' Initializing a service with a proxy providing a SerializableObjectLayer instance.
    Public Sub New()
        MyBase.New(New ObjectServiceProxy())
    End Sub

    Shared Sub New()
        ' Initializing a data access layer (DAL).
        ' ...
    End Sub
End Class

Public Class ObjectServiceProxy
    Inherits SerializableObjectLayerProxyBase
    Protected Overrides Function GetObjectLayer() As SerializableObjectLayer
        Return New SerializableObjectLayer(New UnitOfWork(), True)
    End Function
End Class
