public static List<DomainEventMessage> upcastAndDeserialize(SerializedDomainEventData entry,
                                                            Object aggregateIdentifier,
                                                            Serializer serializer,
                                                            UpcasterChain upcasterChain,
                                                            boolean skipUnknownTypes)

Upcasts and deserializes the given entry using the given serializer and upcasterChain. This code is optimized to deserialize the meta-data only once in case it has been used in the upcasting process.

The list of events returned contains lazy deserializing events for optimization purposes. Events represented with unknown classes are ignored, and not returned.

Parameters:

entry - the entry containing the data of the serialized event

aggregateIdentifier - the original aggregate identifier to use in the deserialized events or null to use the deserialized version

serializer - the serializer to deserialize the event with

upcasterChain - the chain containing the upcasters to upcast the events with

skipUnknownTypes - whether unknown serialized types should be ignored

Returns:

a list of upcast and deserialized events
