MapStorageWithAuth (Keycloak Docs Distribution 21.0.2 API)

All Superinterfaces:

MapStorage<V,M>
```
public interface MapStorageWithAuth<V extends AbstractEntity & UpdatableEntity,M>
extends MapStorage<V,M>
```
Implementing this interface signals that the store can validate credentials. This will be implemented, for example, by a store that supports SPNEGO for Kerberos authentication.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`MapKeycloakTransactionWithAuth<V,M>`	`createTransaction(KeycloakSession session)`	Creates a `MapKeycloakTransaction` object that tracks a new transaction related to this storage.
`boolean`	`supportsCredentialType(String type)`	Determine which credential types a store supports.

- Method Detail
  - supportsCredentialType
```
boolean supportsCredentialType(String type)
```
    Determine which credential types a store supports. This method should be a cheap way to query the store before creating a more expensive transaction and performing an authentication.
    
    Parameters:
    
    type - supported credential type by this store, for example CredentialModel.KERBEROS.
    
    Returns:
    
    true if the credential type is supported by this storage
  - createTransaction
```
MapKeycloakTransactionWithAuth<V,M> createTransaction(KeycloakSession session)
```
    Description copied from interface: MapStorage
    
    Creates a MapKeycloakTransaction object that tracks a new transaction related to this storage. In case of JPA or similar, the transaction object might be supplied by the container (via JTA) or shared same across storages accessing the same database within the same session; in other cases (e.g. plain map) a separate transaction handler might be created per each storage.
    
    Specified by:
    
    createTransaction in interface MapStorage<V extends AbstractEntity & UpdatableEntity,M>
    
    Returns:
    
    See description. Never returns null
