updateLaunchServerInfo(self, serveruri, delayed_exec=0.0)

source code 

This method starts a thread to get the informations about the launch server by the given RCP uri of the launch server. If all informations are retrieved, a launch_server_signal of this class will be emitted. If for given serveruri a thread is already running, it will be inserted to the requested updates. For the same serveruri only one requested update can be stored. On update error the requested update will be ignored. This method is thread safe.

Parameters:
  • serveruri (str) - the URI of the remote launch server
  • delayed_exec (float) - Delay the execution of the request for given seconds.
