java.lang.Object

dk.cloudcreate.essentials.components.eventsourced.aggregates.stateful.StatefulAggregateInMemoryProjector

All Implemented Interfaces:

public class StatefulAggregateInMemoryProjector
extends Object
implements dk.cloudcreate.essentials.components.eventsourced.eventstore.postgresql.InMemoryProjector

Aggregate specific InMemoryProjector
Note: An in memory projection is never associated with a UnitOfWork and any changes to the aggregate won't automatically be persisted. Use the StatefulAggregateRepository for transactional usage.
