Message corresponding to an event. @author shinyak

org.apache.s4.base.EventMessage

Encapsulates application-level events of type {@link Event}.

Indeed, events that are defined at the application level can only be handled by the classloader of the corresponding application.

Includes routing information (application name, stream name), so that this message can be dispatched at the communication level.
org.axonframework.domain.EventMessage
Represents a Message wrapping an Event, which is represented by its payload. An Event is a representation of an occurrence of an event (i.e. anything that happened any might be of importance to any other component) in the application. It contains the data relevant for components that need to act based on that event. @param < T> The type of payload contained in this Message @author Allard Buijze @see DomainEventMessage @since 2.0
