|---|---|
| Options | Gets the options of the current CacheInvalidator. |
Methods
| Name | Description |
|---|---|
| InvalidateDependencyAsyncCore(String, CancellationToken) | 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. |
| InvalidateDependencyCore(String) | 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. |
| OnMessageReceived(String) | Implementations of CacheInvalidator must call this method when an invalidation message is received. |
| RemoveItemAsyncCore(String, CancellationToken) | 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. |
| RemoveItemCore(String) | 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. |
| SendMessageAsync(String, CancellationToken) | Sends an invalidation message over the message bus of the implementation. |
