  2. abstract def validate(priorEvent: Option[PossiblyIgnoredSerializedEvent], event: OrdinarySerializedEvent, sequencerId: SequencerId): EitherT[FutureUnlessShutdown, SequencedEventValidationError[Nothing], Unit]

    Validates that the supplied event is suitable for processing from the prior event.

    Validates that the supplied event is suitable for processing from the prior event. If the event is successfully validated it becomes the event that the event in a following call will be validated against. We currently assume this is safe to do as if the event fails to be handled by the application then the sequencer client will halt and will need recreating to restart event processing.

  3. abstract def validateOnReconnect(priorEvent: Option[PossiblyIgnoredSerializedEvent], reconnectEvent: OrdinarySerializedEvent, sequencerId: SequencerId): EitherT[FutureUnlessShutdown, SequencedEventValidationError[Nothing], Unit]

    Validates a sequenced event when we reconnect against the prior event supplied to SequencedEventValidatorFactory.create

  4. abstract def validatePekko[E](subscription: SequencerSubscriptionPekko[E], priorReconnectEvent: Option[OrdinarySerializedEvent], sequencerId: SequencerId)(implicit arg0: Pretty[E], traceContext: TraceContext): SequencerSubscriptionPekko[SequencedEventValidationError[E]]

    Add event validation to the given com.digitalasset.canton.sequencing.client.SequencerSubscriptionPekko.

    Add event validation to the given com.digitalasset.canton.sequencing.client.SequencerSubscriptionPekko. Stuttering is interpreted as reconnection and validated accordingly.

    The returned com.digitalasset.canton.sequencing.client.SequencerSubscriptionPekko completes after the first event validation failure or the first subscription error. It does not stutter any more.

    priorReconnectEvent

    The sequenced event at which the reconnection happens. If scala.Some$, the first received event must be the same
