  • Method Details

    • commit

      IVersion commit(IEpoch epoch)
      Commits the pending transient state at the specified epoch.

      This automatically creates a new transient, writable state.

      Thread-safety: unless specific otherwise by the implementing class, it is not thread-safe to call commit(IEpoch) and rollback() concurrently.

      Parameters:
      epoch - the epoch associated with this commit
      Returns:
      the version that prevails after this commit (possibly an untouched current version if the commit had absolutely no impact on the state)

    • rollback

      void rollback()
      Rolls back the changes that have been written in the transient state.

      Thread-safety: unless specific otherwise by the implementing class, it is not thread-safe to call commit(IEpoch) and rollback() concurrently.
