      public abstract <T extends io.prometheus.client.Collector> T registerIfNotExist(String metricName, T collector)
      Register a metric if it does not yet exist. If it does exist, then return the existing metric. Currently, only needed by the LocalRunner when running in threaded and exposing metrics via a http server. This method helps resolve the conflict in which multiple instances within the LocalRunner process try to register the same metric.

      参数:

      返回:
      If the metric with the name `metricName` already exists, return the existing metric object. If not, return null
