Method Details

__init__(self, masteruri, parent=None)

master_info(self, master_info)

source code 

Sets the new master information. To determine whether a node is running the PID and his URI are needed. The PID of remote nodes (host of the ROS master and the node are different) will be not determine by discovering. Thus this information must be obtain from other MasterInfo object and stored while updating.

Parameters:

Start nodes given in a list by their names.

Parameters:
  • nodes ([str]) - a list with full node names
