  RepeatInternalStateSupport |
  RepeatSynchronizationManager | Global variable support for repeat clients.
  RepeatTemplate | Simple implementation and base class for batch templates implementing `RepeatOperations`.
  ResultHolderResultQueue | An implementation of the `ResultQueue` that throttles the number of expected results, limiting it to a maximum at any given time.
  TaskExecutorRepeatTemplate | Provides `RepeatOperations` support including interceptors that can be used to modify or monitor the behaviour at run time. This implementation is sufficient to be used to configure transactional behaviour for each item by making the `RepeatCallback` transactional, or for the whole batch by making the execute method transactional (but only then if the task executor is synchronous). This class is thread-safe if its collaborators are thread-safe (interceptors, terminationPolicy, callback).
  ThrottleLimitResultQueue<T> | An implementation of the `ResultQueue` that throttles the number of expected results, limiting it to a maximum at any given time.
