class SyncDomainEphemeralState extends SyncDomainEphemeralStateLookup with NamedLogging with CloseableHealthComponent with AtomicHealthComponent

The state of a synchronization domain that is kept only in memory and must be reconstructed after crashes and fatal errors from the SyncDomainPersistentState. The ephemeral state can be kept across network disconnects provided that the local processing continues as far as possible.

    Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

    DO NOT CALL this.close as part of f, because it will result in a deadlock.

    Performs the EitherT[Future] given by etf unless a shutdown has been initiated, in which case the provided error is returned instead. Both etf and the error are lazy; etf is only evaluated if there is no shutdown, the error only if we're shutting down.

    Performs the Future given by f unless a shutdown has been initiated. The future is lazy and not evaluated during shutdown. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingEitherT).

    returns

    The future completes with com.digitalasset.canton.lifecycle.UnlessShutdown.AbortedDueToShutdown if a shutdown has been initiated. Otherwise the result of the task wrapped in com.digitalasset.canton.lifecycle.UnlessShutdown.Outcome.

    Triggers a refresh of the component's state, using newState to determine the new state. May return before the newState has been evaluated and the listeners have been poked.

    Note that listeners need not be poked about every state change; it suffices that they are poked eventually after each state change. So if there are frequent updates to the state, possibly from concurrent calls, then the listeners may never see some intermediate states.
