## Interface UserCredentialStore.Streams

- All Superinterfaces:
    Provider, UserCredentialStore
  All Known Subinterfaces:
    UserCredentialManager.Streams
  All Known Implementing Classes:
    JpaUserCredentialStore, JpaUserFederatedStorageProvider, JpaUserProvider, MapUserProvider, UserCredentialStoreManager
  Enclosing interface:
    UserCredentialStore

      public static interface UserCredentialStore.Streams
      extends UserCredentialStore

  The `UserCredentialStore.Streams` interface makes all collection-based methods in `UserCredentialStore` default by providing implementations that delegate to the `Stream`-based variants instead of the other way around.

  It allows for implementations to focus on the `Stream`-based approach for processing sets of data and benefit from the potential memory and performance optimizations of that approach.
