StateLockingRepository<C, S, V, CM, SM> class abstract interface

Stores and retrieves aggregate state with optimistic locking.

The repository returns the version of fetched state. Saves can use that version to reject updates when the stored state changed concurrently.

  • C: command type
  • S: state type
  • V: version type
  • CM: command metadata type
  • SM: state metadata type
