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

Class StatefulAggregateRepository.DefaultStatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE extends StatefulAggregate<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>>

java.lang.Object

dk.cloudcreate.essentials.components.eventsourced.aggregates.stateful.StatefulAggregateRepository.DefaultStatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>

Type Parameters:

ID - the aggregate ID type

AGGREGATE_IMPL_TYPE - the concrete aggregate type (MUST be a subtype of StatefulAggregate)

All Implemented Interfaces:

StatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>

Enclosing interface:

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

public static class StatefulAggregateRepository.DefaultStatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE extends StatefulAggregate<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>>
extends Object
implements StatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>

Default StatefulAggregateRepository implementation. You can extend this class directly if you need to expand the supported method or use StatefulAggregateRepository.from(ConfigurableEventStore, AggregateEventStreamConfiguration, StatefulAggregateInstanceFactory, Class, Class) to create a default instance

The EventStore that's being used for support

toString

public String toString()

Overrides:

toString in class Object

tryLoad

public Optional<AGGREGATE_IMPL_TYPE> tryLoad(ID aggregateId,
                                             Optional<dk.cloudcreate.essentials.components.eventsourced.eventstore.postgresql.types.EventOrder> expectedLatestEventOrder)

Description copied from interface: StatefulAggregateRepository

Try to load an StatefulAggregate instance with the specified aggregateId from the underlying EventStore
If the aggregate instance exists it will be associated with the UnitOfWorkFactory.getRequiredUnitOfWork() and any changes to will be tracked and will be persisted to the underlying EventStore when the UnitOfWork is committed.

Specified by:

tryLoad in interface StatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE extends StatefulAggregate<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>>

Parameters:

aggregateId - the id of the aggregate we want to load

expectedLatestEventOrder - option with the expected Event.eventOrder() of the last event stored in relation to the given aggregate instance (if any)

Returns:

an Optional with the matching StatefulAggregate instance if it exists, otherwise it will return an Optional.empty()

save

public AGGREGATE_IMPL_TYPE save(AGGREGATE_IMPL_TYPE aggregate)

Description copied from interface: StatefulAggregateRepository

Save/Associate a newly created and not yet persisted StatefulAggregate instance with the UnitOfWorkFactory.getRequiredUnitOfWork()
Any changes to will be tracked and will be persisted to the underlying EventStore when the UnitOfWork is committed.

Specified by:

save in interface StatefulAggregateRepository<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE extends StatefulAggregate<ID,EVENT_TYPE,AGGREGATE_IMPL_TYPE>>

Parameters:

aggregate - the aggregate instance to persist to the underlying EventStore

Returns:

the persisted aggregate
