Class GrpcBackedDomainEventData

java.lang.Object

org.axonframework.axonserver.connector.event.axon.GrpcBackedDomainEventData

All Implemented Interfaces:

org.axonframework.eventhandling.DomainEventData<byte[]>, org.axonframework.eventhandling.EventData<byte[]>

public class GrpcBackedDomainEventData
extends Object
implements org.axonframework.eventhandling.DomainEventData<byte[]>

DomainEventData implementation that retrieves its raw data from a protobuf Event message.

This implementation strictly breaks the contract of DomainEventData, in that the returned SerializedObject for MetaData does not contain the byte array representation of the metadata, but the MetaDataMap defined in the protobuf message.

Since:

4.0
