Class SimpleSerializedDomainEventData

java.lang.Object

org.axonframework.eventstore.jpa.SimpleSerializedDomainEventData

All Implemented Interfaces:

SerializedDomainEventData

public class SimpleSerializedDomainEventData
extends Object
implements SerializedDomainEventData

Simple implementation of the SerializedDomainEventData class, used to reduce memory consumptions by queries accessing Event Entries. Querying from them directly will cause the EntityManager to keep a reference to them, preventing them from being garbage collected.

Since:

2.0

Parameters:

eventIdentifier - The identifier of the event

aggregateIdentifier - The identifier of the aggregate

sequenceNumber - The sequence number of the event

timestamp - The timestamp of the event (format must be supported by DateTime.DateTime(Object))

payloadType - The type identifier of the serialized payload

payloadRevision - The revision of the serialized payload

payload - The serialized representation of the event

metaData - The serialized representation of the meta data
