Class AbstractStorageManager<ProviderType extends Provider,StorageProviderModelType extends CacheableStorageProviderModel>

java.lang.Object
org.keycloak.storage.AbstractStorageManager<ProviderType,StorageProviderModelType>
Type Parameters:
ProviderType - This type will be used for looking for factories that produce instances of desired providers
StorageProviderModelType - Type of model used for creating provider, it needs to extend CacheableStorageProviderModel as it has isEnabled() method and also extend PrioritizedComponentModel which is required for sorting providers based on its priorities
Direct Known Subclasses:
ClientScopeStorageManager, GroupStorageManager, LegacyUserCredentialManager, UserStorageManager

      Type Parameters:
      R - Result of applyFunction
      Parameters:
      realm - realm
      capabilityInterface - class of desired capabilityInterface. For example, GroupLookupProvider or UserQueryProvider
