Class ElementContainerCacheRefresher

Provides cache refresh functionality for element containers (folders).

Inheritance

object

CacheRefresherBase<ElementContainerCacheRefresherNotification>

JsonCacheRefresherBase<ElementContainerCacheRefresherNotification, ElementContainerCacheRefresher.JsonPayload>

PayloadCacheRefresherBase<ElementContainerCacheRefresherNotification, ElementContainerCacheRefresher.JsonPayload>

Namespace: Umbraco.Cms.Core.Cache

Assembly: Umbraco.Core.dll

Syntax

public sealed class ElementContainerCacheRefresher : PayloadCacheRefresherBase<ElementContainerCacheRefresherNotification, ElementContainerCacheRefresher.JsonPayload>, IPayloadCacheRefresher<ElementContainerCacheRefresher.JsonPayload>, IJsonCacheRefresher, ICacheRefresher, IDiscoverable

Remarks

A deleted container's node id is never reused, so its key→id mapping in IIdKeyMap must be evicted on every server. Otherwise a container recreated under the same key resolves to the stale id and the element tree's children query returns nothing until the next app restart. This refresher only evicts the id/key map - element data is unaffected by container changes, so it deliberately avoids the broader invalidation performed by ElementCacheRefresher.
