public class NullCachingBackend : CachingBackend
The NullCachingBackend type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | NullCachingBackend | Initializes a new instance of the NullCachingBackend class |
Properties| Name | Description | |
|---|---|---|
 | Id |
Gets the Guid of the current CachingBackend.
(Inherited from CachingBackend.) |
 | Logger |
Gets the Logger that implementations can use to emit
log records.
(Inherited from CachingBackend.) |
| Status | (Inherited from CachingBackend.) |
| SupportedFeatures |
Gets the set of features supported by the current CachingBackend.
(Inherited from CachingBackend.) |
| ValueAdapters |
Gets the factory of value adapters (IValueAdapter), which allow for instance to cache things like Stream or IEnumerable,
which could not be otherwise cached.
(Inherited from CachingBackend.) |
Methods| Name | Description | |
|---|---|---|
| Clear |
Clears the cache.
(Inherited from CachingBackend.) |
| ClearAsync |
Asynchronously clears the cache.
(Inherited from CachingBackend.) |
 | ClearAsyncCore |
Asynchronously clears the cache. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked.
(Inherited from CachingBackend.) |
| ClearCore |
Clears the cache. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked.
(Overrides CachingBackend.ClearCore().) |
| ContainsDependency |
Determines whether the cache contains a given dependency.
(Inherited from CachingBackend.) |
| ContainsDependencyAsync |
Asynchronously determines whether the cache contains a given dependency.
(Inherited from CachingBackend.) |
| ContainsDependencyAsyncCore |
Asynchronously determines whether the cache contains a given dependency. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Inherited from CachingBackend.) |
| ContainsDependencyCore |
Determines whether the cache contains a given dependency. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Overrides CachingBackend.ContainsDependencyCore(String).) |
| ContainsItem |
Determines whether the cache contains an item of a given key.
(Inherited from CachingBackend.) |
| ContainsItemAsync |
Asynchronously determines whether the cache contains an item of a given key.
(Inherited from CachingBackend.) |
| ContainsItemAsyncCore |
Asynchronously determines whether the cache contains an item of a given key. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Inherited from CachingBackend.) |
| ContainsItemCore |
Determines whether the cache contains an item of a given key. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Overrides CachingBackend.ContainsItemCore(String).) |
| CreateFeatures |
Creates a CachingBackendFeatures object, which describes set of features implemented by the back-end.
This method is invoked the first time the SupportedFeatures property is evaluated. The result is then cached.
(Inherited from CachingBackend.) |
| Dispose() |
Synchronously disposes the current CachingBackend.
(Inherited from CachingBackend.) |
| Dispose(Boolean) |
Synchronously disposes the current CachingBackend, with a parameter instructing whether this method is called because
of a call to the Dispose() method or because of object finalizing.
(Inherited from CachingBackend.) |
| DisposeAsync |
Asynchronously dispose the current CachingBackend.
(Inherited from CachingBackend.) |
| DisposeAsyncCore |
Asynchronously disposes the current CachingBackend. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked.
(Inherited from CachingBackend.) |
| DisposeCore |
Synchronously disposes the current CachingBackend. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked.
(Inherited from CachingBackend.) |
| GetItem |
Gets a cache item given its key.
(Inherited from CachingBackend.) |
| GetItemAsync |
Asynchronously gets a cache item given its key.
(Inherited from CachingBackend.) |
| GetItemAsyncCore |
Asynchronously gets a cache item given its key. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Inherited from CachingBackend.) |
| GetItemCore |
Gets a cache item given its key. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Overrides CachingBackend.GetItemCore(String, Boolean).) |
| InvalidateDependency |
Removes from the cache all items that have a specific dependency.
(Inherited from CachingBackend.) |
| InvalidateDependencyAsync |
Asynchronously removes from the cache all items that have a specific dependency. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Inherited from CachingBackend.) |
| InvalidateDependencyAsyncCore |
Asynchronously removes from the cache all items that have a specific dependency. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Inherited from CachingBackend.) |
| InvalidateDependencyCore |
Removes from the cache all items that have a specific dependency. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Overrides CachingBackend.InvalidateDependencyCore(String).) |
| OnDependencyInvalidated(CacheDependencyInvalidatedEventArgs) |
Raises the DependencyInvalidated event given a CacheDependencyInvalidatedEventArgs.
(Inherited from CachingBackend.) |
| OnDependencyInvalidated(String, Guid) |
Raises the DependencyInvalidated event , but lazily instantiates the CacheDependencyInvalidatedEventArgs
if there is an event client.
(Inherited from CachingBackend.) |
| OnItemRemoved(CacheItemRemovedEventArgs) |
Raises the ItemRemoved event given a CacheItemRemovedEventArgs.
(Inherited from CachingBackend.) |
| OnItemRemoved(String, CacheItemRemovedReason, Guid) |
Raises the ItemRemoved event, but lazily instantiates the CacheItemRemovedEventArgs
if there is an event client.
(Inherited from CachingBackend.) |
| RemoveItem |
Removes a cache item from the cache given its key.
(Inherited from CachingBackend.) |
| RemoveItemAsync |
Asynchronously removes a cache item from the cache given its key.
(Inherited from CachingBackend.) |
| RemoveItemAsyncCore |
Asynchronously removes a cache item from the cache given its key. This protected method is part of the implementation API and is meant to be overridden in user code, not invoked. Arguments are already validated by the consumer API.
(Inherited from CachingBackend.) |
| RemoveItemCore |

have completed.
(Inherited from CachingBackend.) |
Events| Name | Description | |
|---|---|---|
 | DependencyInvalidated |
Events raised when a dependency is invalidated. Check the Events
property to see if the current CachingBackend supports events.
(Inherited from CachingBackend.) |
| ItemRemoved |
Event raised when a cache item is removed from the cache. Check the Events
property to see if the current CachingBackend supports events.
(Inherited from CachingBackend.) |
