Class DefaultRepositoryCachePolicy<TEntity, TId>

Represents the default cache policy.

Inheritance

object

RepositoryCachePolicyBase<TEntity, TId>

Namespace: Umbraco.Cms.Core.Cache

Assembly: Umbraco.Infrastructure.dll

Syntax

public class DefaultRepositoryCachePolicy<TEntity, TId> : RepositoryCachePolicyBase<TEntity, TId>, IRepositoryCachePolicy<TEntity, TId> where TEntity : class, IEntity

Type Parameters

Name	Description
TEntity	The type of the entity.
TId	The type of the identifier.

Remarks

The default cache policy caches entities with a 5 minutes sliding expiration.

Each entity is cached individually.

If options.GetAllCacheAllowZeroCount then a 'zero-count' array is cached when GetAll finds nothing.

If options.GetAllCacheValidateCount then we check against the db when getting many entities.
