Object

com.lightbend.lagom.javadsl.persistence.AggregateEventTag<Event>

public final class AggregateEventTag<Event extends AggregateEvent<Event>>
extends Object

The base type of PersistentEntity events may implement this interface to make the events available for read-side processing.

The tag should be unique among the event types of the service.

The class name can be used as tag, but note that it is needed to retain the original tag when the class name is changed because the tag is part of the store event data.
