    String aggregateIdentifier = "1234";
    lengthy startFrom = 0;
    String eventType = "org.pattern.mannequin.occasions.MyEvent";
    Class projectorClass = MyProjector.class;
    
    AnnotationEventHandlerAdapter eventHandlerAdapter = new AnnotationEventHandlerAdapter(projectorClass);
    AreaEventStream occasionStream = eventStore.learnEvents(aggregateIdentifier, startFrom);
    occasionStream.asStream()
        .filter(occasion -> {
            // add any sort of filtering based mostly on the occasion right here
            return occasion.getType() == eventType;
        })
        .forEach(event1 -> {
            attempt {
                eventHandlerAdapter.deal with(event1);
            } catch (Exception e) {
                e.printStackTrace();
            }
        });
