  an object that will be sent to IMetricsConsumer.handleDataPoints(org.apache.storm.metric.api.IMetricsConsumer.TaskInfo,java.util.Collection). If null is returned nothing will be sent. If this value can be reset, like with a counter, a side effect of calling this should be that the value is reset.
