Example 1 with FlowEvent

use of com.twitter.hraven.FlowEvent in project ambrose by twitter.

the class HRavenStatsReadService method getEventsSinceId.

@SuppressWarnings("rawtypes")
@Override
public List<Event> getEventsSinceId(String workflowId, int eventId, int maxEvents) throws IOException {
    Preconditions.checkArgument(maxEvents > 0);
    WorkflowId id = WorkflowId.parseString(workflowId);
    FlowEventKey flowEventKey = new FlowEventKey(toFlowKey(id), eventId);
    List<FlowEvent> flowEventList = flowEventService.getFlowEventsSince(flowEventKey);
    // TODO push this limit into the FlowEventService
    int numElems = 0;
    List<Event> workflowEvents = Lists.newArrayListWithCapacity(maxEvents);
    for (FlowEvent flowEvent : flowEventList) {

        String eventDataJson = flowEvent.getEventDataJSON();
        try {
            Event event = Event.fromJson(eventDataJson);
            numElems++;
            workflowEvents.add(event);
