Examples of DomainEventStream

org.axonframework.domain.DomainEventStream
The DomainEventStream represents a stream of historical domain events. The order of events in this stream must represent the actual chronological order in which the events happened. A DomainEventStream may provide access to all events (from the first to the most recent) or any subset of these. @author Allard Buijze @since 0.1
