Interface StatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE extends StatefulAggregate<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>>

Type Parameters:

ID - the aggregate id type (aka stream-id)

EVENT_TYPE - the type of event

AGGREGATE_IMPL_TYPE - the aggregate implementation type

All Known Implementing Classes:

StatefulAggregateRepository.DefaultStatefulAggregateRepository

public interface StatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE extends StatefulAggregate<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>>

Opinionated Aggregate Repository that's built to persist and load a specific StatefulAggregate type in combination with EventStore, UnitOfWorkFactory and a StatefulAggregateInstanceFactory.
You can use the from(ConfigurableEventStore, AggregateEventStreamConfiguration, StatefulAggregateInstanceFactory, Class) to create a new StatefulAggregateRepository instance that supports the most common repository method.
Alternatively you can extend from the StatefulAggregateRepository.DefaultStatefulAggregateRepository and add your own special methods
