Class ElementContainerDeletedDistributedCacheNotificationHandler

Invalidates element caches when an element container (folder) is deleted, so that its key→id mapping is evicted from IIdKeyMap on every server.

Inheritance

object

DistributedCacheNotificationHandlerBase<EntityContainer, EntityContainerDeletedNotification>

DeletedDistributedCacheNotificationHandlerBase<EntityContainer, EntityContainerDeletedNotification, EntityContainer>

DeletedDistributedCacheNotificationHandlerBase<EntityContainer, EntityContainerDeletedNotification>

Namespace: Umbraco.Cms.Core.Cache

Assembly: Umbraco.Core.dll

Syntax

public sealed class ElementContainerDeletedDistributedCacheNotificationHandler : DeletedDistributedCacheNotificationHandlerBase<EntityContainer, EntityContainerDeletedNotification>, IDistributedCacheNotificationHandler<EntityContainerDeletedNotification>, INotificationHandler<EntityContainerDeletedNotification>, IDistributedCacheNotificationHandler, INotificationHandler

Remarks

Element container deletions only publish EntityContainerDeletedNotification and an ElementTreeChangeNotification for the contained elements - never for the container node itself, so without this handler the container's stale id/key mapping survives until the next app restart (see #23072).
