Namespace: DevExpress.ExpressApp.Security.ClientServer
Assembly: DevExpress.ExpressApp.Security.Xpo.v26.1.dll
NuGet Package: DevExpress.ExpressApp.Security.Xpo
Declaration
public class SecuredObjectSpaceProvider :
XPObjectSpaceProvider,
INonsecuredObjectSpaceProviderRemarks
The following topic demonstrates how to create and use the SecuredObjectSpaceProvider: How to: Use the Integrated Mode of the Security System in Non-XAF Applications.
XAF uses an Object Space Provider to create Object Spaces. The following Object Space Provider types are included in XAF:
| Object Space Provider | Object Space | Application Builder Method |
|---|---|---|
| EFCoreObjectSpaceProvider<TDbContext> | EFCoreObjectSpace | AddEFCore |
| XPObjectSpaceProvider | XPObjectSpace | AddXpo |
| SecuredEFCoreObjectSpaceProvider<TDbContext> | SecuredEFCoreObjectSpace | AddSecuredEFCore |
SecuredObjectSpaceProvider |
SecuredXPObjectSpace | AddSecuredXpo |
| NonPersistentObjectSpaceProvider | NonPersistentObjectSpace | AddNonPersistent |
XAF applications configure Object Space Providers through the Application Builder’s ObjectSpaceProviders properties: IBlazorApplicationBuilder.ObjectSpaceProviders and IWinApplicationBuilder.ObjectSpaceProviders. When you create an application with the Template Kit, it registers Object Space Providers for the selected preset.
Refer to the following topic for instructions on how to add custom Object Space Providers to your application: Custom Object Space Provider.
Note
When multiple Object Space Providers are registered in the application, the ModuleUpdater.UpdateDatabaseAfterUpdateSchema method is executed multiple times, once for each registered Provider. In this method, before accessing an object of a particular type, check if the current Object Space supports this type using the IObjectSpace.CanInstantiate method.
