java.lang.Object org.axonframework.eventstore.supporting.TimestampCutoffReadonlyEventStore
public class TimestampCutoffReadonlyEventStore
Takes a backend, both EventStore
and EventStoreManagement
, and functions as a filter based on a
DateTime
.
Only events that are older than the provided cut-off datetime are returned to caller or handed to an
EventVisitor
.
This is a read-only implementation. Appending events is not allowed.

EventVisitor.doWithEvent(org.axonframework.domain.DomainEventMessage)
for each event found. Events of a single aggregate are guaranteed to be ordered by their sequence number.
Implementations are encouraged, though not required, to supply events in the absolute chronological order.
Processing stops when the visitor throws an exception.
