## RevocationCutoffRegistry Class

Keeps revocation cutoffs in the same entity storage the rest of the server's short\-lived state lives in\.

```csharp
public class RevocationCutoffRegistry : Abblix.Oidc.Server.Features.Storages.IRevocationCutoffRegistry
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → RevocationCutoffRegistry

Implements [IRevocationCutoffRegistry](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Storages.IRevocationCutoffRegistry 'Abblix\.Oidc\.Server\.Features\.Storages\.IRevocationCutoffRegistry')
### Constructors

## RevocationCutoffRegistry\(IEntityStorage, IEntityStorageKeyFactory\) Constructor {#Abblix.Oidc.Server.Features.Storages.RevocationCutoffRegistry.RevocationCutoffRegistry(Abblix.Oidc.Server.Features.Storages.IEntityStorage,Abblix.Oidc.Server.Features.Storages.IEntityStorageKeyFactory)}

Keeps revocation cutoffs in the same entity storage the rest of the server's short\-lived state lives in\.

```csharp
public RevocationCutoffRegistry(Abblix.Oidc.Server.Features.Storages.IEntityStorage storage, Abblix.Oidc.Server.Features.Storages.IEntityStorageKeyFactory keyFactory);
```
#### Parameters

###### `storage` [IEntityStorage](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Storages.IEntityStorage 'Abblix\.Oidc\.Server\.Features\.Storages\.IEntityStorage') {#Abblix.Oidc.Server.Features.Storages.RevocationCutoffRegistry.RevocationCutoffRegistry(Abblix.Oidc.Server.Features.Storages.IEntityStorage,Abblix.Oidc.Server.Features.Storages.IEntityStorageKeyFactory).storage}

Where the cutoff is written and read\.

###### `keyFactory` [IEntityStorageKeyFactory](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Storages.IEntityStorageKeyFactory 'Abblix\.Oidc\.Server\.Features\.Storages\.IEntityStorageKeyFactory') {#Abblix.Oidc.Server.Features.Storages.RevocationCutoffRegistry.RevocationCutoffRegistry(Abblix.Oidc.Server.Features.Storages.IEntityStorage,Abblix.Oidc.Server.Features.Storages.IEntityStorageKeyFactory).keyFactory}

Names the entry, so a deployment sharing one store across products keeps its
            own namespace\.
### Methods

## RevocationCutoffRegistry\.GetCutoffAsync\(RevocationScope, string, CancellationToken\) Method {#Abblix.Oidc.Server.Features.Storages.RevocationCutoffRegistry.GetCutoffAsync(Abblix.Oidc.Server.Features.Tokens.Revocation.RevocationScope,string,System.Threading.CancellationToken)}
