C# Класс Sage.CacheWrapper

Provides a wrapper around the current System.Web.Caching.Cache, as well as a plain key/value dictionary, so that if System.Web.Caching.Cache is null (as in unit test scenarios), the code using the cache can run without exceptions.

Описание методов

CacheWrapper() публичный Метод

Initializes a new instance of the CacheWrapper class.

public CacheWrapper ( ) : System
Результат	System

CacheWrapper() публичный Метод

Initializes a new instance of the CacheWrapper class using the specified context.

public CacheWrapper ( System.Web.HttpContextBase context ) : System
context	System.Web.HttpContextBase	The current HTTP context.
Результат	System

Get() публичный Метод

Retrieves the specified item from the cache.

public Get ( string key ) : object
key	string	The identifier for the cache item to retrieve.
Результат	object

Insert() публичный Метод

Inserts an object into the cache that has file or key dependencies.

public Insert ( string key, object value, System.Web.Caching.CacheDependency dependencies ) : void
key	string	The cache key that is used to reference the object.
value	object	The object to insert into the cache.
dependencies	System.Web.Caching.CacheDependency	The file or cache key dependencies for the item. When any dependency changes, /// the object becomes invalid and is removed from the cache. If there are no dependencies, this parameter /// contains null.
Результат	void

Insert() публичный Метод

Inserts an object into the cache with dependencies and expiration policies.

public Insert ( string key, object value, System.Web.Caching.CacheDependency dependencies, System.DateTime absoluteExpiration, System.TimeSpan slidingExpiration ) : void
key	string	The cache key that is used to reference the object.
value	object	The object to insert into the cache.
dependencies	System.Web.Caching.CacheDependency	The file or cache key dependencies for the item. When any dependency changes, /// the object becomes invalid and is removed from the cache. If there are no dependencies, this parameter /// contains null.
absoluteExpiration	System.DateTime	The time at which the inserted object expires and is removed from the /// cache. To avoid possible issues with local time such as changes from standard time to daylight saving /// time, use instead of for this parameter value. /// If you are using absolute expiration, the slidingExpiration parameter must be set to /// .
slidingExpiration	System.TimeSpan	The interval between the time that the cached object was last accessed /// and the time at which that object expires. If this value is the equivalent of 20 minutes, the object /// will expire and be removed from the cache 20 minutes after it was last accessed. If you are using /// sliding expiration, the absoluteExpiration parameter must be set to .
Результат	void

Insert() публичный Метод

Inserts an object into the cache with dependencies, expiration and priority policies, and a delegate you can use to notify your application when the inserted item is removed from the Cache.

public Insert ( string key, object value, System.Web.Caching.CacheDependency dependencies, System.DateTime absoluteExpiration, System.TimeSpan slidingExpiration, CacheItemPriority priority, CacheItemRemovedCallback callback ) : void
key	string	The cache key that is used to reference the object.
value	object	The object to insert into the cache.

If you are using /// sliding expiration, the absoluteExpiration parameter must be set to .
priority	CacheItemPriority	The cost of the object relative to other items stored in the cache, as expressed /// by the enumeration. This value is used by the cache when it evicts /// objects; objects with a lower cost are removed from the cache before objects with a higher cost.
callback	CacheItemRemovedCallback	A delegate that will be called before the object is removed from the cache. /// You can use this to update the cached item and ensure that it is not removed from the cache.
