the class BoltInstance method start.

@Override
public void start() {
    TopologyContextImpl topologyContext = helper.getTopologyContext();
    // Initialize the GlobalMetrics
    GlobalMetrics.init(topologyContext, systemConfig.getHeronMetricsExportIntervalSec());
    boltMetrics.registerMetrics(topologyContext);
    // Delegate
    bolt.prepare(topologyContext.getTopologyConfig(), topologyContext, new OutputCollector(collector));
    // Invoke user-defined prepare task hook
    topologyContext.invokeHookPrepare();
    // Init the CustomStreamGrouping
    helper.prepareForCustomStreamGrouping();
    addBoltTasks();
}

Example 2 with OutputCollector
