Interface IObjectInstanceCache

An interface for local, fast caching of object instances.

Namespace: EPiServer.Framework.Cache
Assembly: EPiServer.Framework.dll
Version: 11.20.2
Syntax
public interface IObjectInstanceCache
Remarks

One assumption is that the objects don't need to be serializable - they will be live object instances.

Another assumption is that the items in the cache may be purged at any point-in-time. When you set expiration time the system will only guarantee that the cached item will not be available after the expiration time, but it may be removed before that time depending on the underlying cache implementation.
