doStop

protected void doStop()

Gracefully shut down. If HttpTransportSettings.SETTING_HTTP_SERVER_SHUTDOWN_GRACE_PERIOD is zero, the default, then forcefully close all open connections immediately. Serially run through the following steps: 1) Stop listening for new HTTP connections, which means no new HttpChannel are added to the httpChannels list 2) Add the Connection: close response header to all new requests on existing httpChannels and close the HttpChannel after the new request completes 3) If grace period is set, wait for all httpChannels to close via 2 for up to the configured grace period, shutdownGracePeriodMillis. If all connections are closed before the expiration of the grace period, stop waiting early. 4) Close all open httpChannels even if requests are in flight.

Specified by:
