Class SimpleSerializedDomainEventData<T>

java.lang.Object
  org.axonframework.eventstore.jpa.SimpleSerializedDomainEventData<T>

Type Parameters:

T - The data type expected for the serialized objects

All Implemented Interfaces:

SerializedDomainEventData<T>

public class SimpleSerializedDomainEventData<T>
extends Object
implements SerializedDomainEventData<T>

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

Constructor Summary

SimpleSerializedDomainEventData(String eventIdentifier, String aggregateIdentifier, long sequenceNumber, Object timestamp, SerializedObject<T> serializedPayload, SerializedObject<T> serializedMetaData)
Initialize an instance using given properties.

SimpleSerializedDomainEventData(String eventIdentifier, String aggregateIdentifier, long sequenceNumber, Object timestamp, String payloadType, String payloadRevision, T payload, T metaData)
Initialize an instance using given properties.

Method Summary

Object	getAggregateIdentifier() Returns the Identifier of the Aggregate to which the Event was applied.
String	getEventIdentifier() Returns the identifier of the serialized event.
SerializedObject<T>	getMetaData() Returns the serialized data of the MetaData of the serialized Event.
SerializedObject<T>	getPayload() Returns the serialized data of the Event Message's payload.
long	getSequenceNumber() Returns the sequence number of the event in the aggregate.
org.joda.time.DateTime	getTimestamp() Returns the timestamp at which the event was first created.

Constructor Detail

SimpleSerializedDomainEventData

public SimpleSerializedDomainEventData(String eventIdentifier,
                                       String aggregateIdentifier,
                                       long sequenceNumber,
                                       Object timestamp,
                                       String payloadType,
                                       String payloadRevision,
                                       T payload,
                                       T metaData)

Initialize an instance using given properties. This constructor assumes the default SerializedType for meta data (name = 'org.axonframework.domain.MetaData' and revision = null).

Note that the given timestamp must be in a format supported by DateTime#DateTime(Object)}.

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

SimpleSerializedDomainEventData

public SimpleSerializedDomainEventData(String eventIdentifier,
                                       String aggregateIdentifier,
                                       long sequenceNumber,
                                       Object timestamp,
                                       SerializedObject<T> serializedPayload,
                                       SerializedObject<T> serializedMetaData)

Initialize an instance using given properties. In contrast to the other constructor, this one allows to explicitly indicate the SerializedType used to represent MetaData.

Note that the given timestamp must be in a format supported by DateTime#DateTime(Object)}.

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))

serializedPayload - The serialized representation of the event

serializedMetaData - The serialized representation of the meta data
