GenericTrackedDomainEventMessage

public GenericTrackedDomainEventMessage(TrackingToken trackingToken,
                                        DomainEventMessage<T> delegate)

Initialize a DomainEventMessage originating from an aggregate.

Parameters:

trackingToken - Tracking token of the event

delegate - Delegate domain event containing other event data

GenericTrackedDomainEventMessage

public GenericTrackedDomainEventMessage(TrackingToken trackingToken,
                                        String type,
                                        String aggregateIdentifier,

                                        Supplier<Instant> timestamp)

Initialize a DomainEventMessage originating from an Aggregate using existing data. The timestamp of the event is supplied lazily to prevent unnecessary deserialization of the timestamp.

Parameters:

trackingToken - Tracking token of the event

type - The domain type

aggregateIdentifier - The identifier of the aggregate generating this message

sequenceNumber - The message's sequence number

delegate - The delegate message providing the payload, metadata and identifier of the event

timestamp - The event's timestamp supplier
