Example 1 with EventSource

use of org.qi4j.library.eventsourcing.domain.source.EventSource in project qi4j-sdk by Qi4j.

the class JdbmEventStoreServiceTest method testDomainEvent.

@Test
public void testDomainEvent() throws UnitOfWorkCompletionException, IOException {
    UnitOfWork uow = module.newUnitOfWork(UsecaseBuilder.newUsecase("Create entity"));
    TestEntity entity = uow.newEntity(TestEntity.class);
    uow.complete();
    int count = 10;
    for (int i = 0; i < count; i++) {
        uow = module.newUnitOfWork(UsecaseBuilder.newUsecase("Change description"));
        uow.setMetaInfo(new Principal() {

            public String getName() {
                return "administrator";
            }
        });
        entity = uow.get(entity);
        entity.changeDescription("New description");
        uow.complete();
    }
    EventSource source = (EventSource) module.findService(EventSource.class).get();
    source.events(0, Long.MAX_VALUE).transferTo(Transforms.map(new Function<UnitOfWorkDomainEventsValue, String>() {

        public String map(UnitOfWorkDomainEventsValue unitOfWorkDomainEventsValue) {
            return unitOfWorkDomainEventsValue.toString();
        }
    }, Outputs.systemOut()));
}

Example 2 with EventSource
