public class InitialEventRepresentation extends Object implements IntermediateEventRepresentation
IntermediateEventRepresentation
that contains the original serialized payload and
metadata before these have been upcast. Usually there is one InitialEventRepresentation
per event entry from
the data store.Constructor and Description |
