  <p>Sample code:
  
  <pre><code>
  try (NotificationChannelServiceClient notificationChannelServiceClient = NotificationChannelServiceClient.create()) {
  ProjectName name = ProjectName.of("[PROJECT]");
  for (NotificationChannel element : notificationChannelServiceClient.listNotificationChannels(name.toString()).iterateAll()) {
  // doThingsWith(element);
  }
  }
  </code></pre>
  
  @param name The project on which to execute the request. The format is `projects/[PROJECT_ID]`.
  That is, this names the container in which to look for the notification channels; it does
  not name a specific channel. To query a specific channel by REST resource name, use the
  [`GetNotificationChannel`][google.monitoring.v3.NotificationChannelService.GetNotificationChannel]
  operation.
  @throws com.google.api.gax.rpc.ApiException if the remote call fails
