Interface IInfoByIdProvider<TInfo>

Namespace

CMS.DataEngine

Assembly

CMS.DataEngine.dll

Declares a member for retrieval of info objects by their ID.

Use this interface when composing a custom provider interface. A custom provider interface can be associated with the provider using the ProviderInterfaceAttribute.

The system registers corresponding TInfo provider implementation under the custom interface into the IoC container as part of the RegisterObjectType(string, ObjectTypeInfo, Type, bool, bool) method.

Unlike with IInfoProvider<TInfo> the system does not register the provider implementation under this interface (i.e. this interface is designed to be a part of other interfaces).

public interface IInfoByIdProvider<TInfo> where TInfo : AbstractInfoBase<TInfo>, new()

Type Parameters

TInfo

Type of info object managed by the provider.
