Открытые методы

Метод	Описание
AddImageToCacheAsync ( Stream stream, string contentType ) : System.Threading.Tasks.Task	Adds the image to the cache in an asynchronous manner.
CreateCachedFileNameAsync ( ) : Task	Gets a string identifying the cached file name.
IsNewOrUpdatedAsync ( ) : Task	Gets a value indicating whether the image is new or updated in an asynchronous manner.
RewritePath ( HttpContext context ) : void	Rewrites the path to point to the cached image.
TrimCacheAsync ( ) : System.Threading.Tasks.Task	Trims the cache of any expired items in an asynchronous manner.

Защищенные методы

Метод	Описание
AugmentSettings ( string>.Dictionary settings ) : void	Provides a means to augment the cache settings taken from the configuration in derived classes. This allows for configuration of cache objects outside the normal configuration files, for example by using app settings in the Azure platform.
ImageCacheBase ( string requestPath, string fullPath, string querystring ) : System	Initializes a new instance of the ImageCacheBase class.
IsExpired ( System.DateTime creationDate ) : bool	Gets a value indicating whether the given images creation date is out with the prescribed limit.

Приватные методы

Метод	Описание
AugmentSettingsCore ( string>.Dictionary settings ) : string>.Dictionary	Provides an entry point to augmentation of the Settings dictionary
