Class ROSLaunchChildHandler

object --+ | rosgraph.xmlrpc.XmlRpcHandler --+ | ROSLaunchBaseHandler --+ | ROSLaunchChildHandler

XML-RPC API implementation for child roslaunches NOTE: the client handler runs a process monitor so that it can track processes across requests

Method Details

init(self, run_id, name, server_uri, pm, sigint_timeout=15.0, sigterm_timeout=2.0)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

server_uri (str) - XML-RPC URI of server
pm (ProcessMonitor) - process monitor to use
sigint_timeout (float) - The SIGINT timeout used when killing nodes (in seconds).
sigterm_timeout (float) - The SIGTERM timeout used when killing nodes if SIGINT does not stop the node ( in seconds).

Raises:

RLException - If parameters are invalid

Overrides: object.__init__

shutdown(self)

source code

Returns: int, str, int: code, msg, ignore

launch(self, launch_xml)

source code

Launch the roslaunch XML file. Because this is a child roslaunch, it will not set parameters nor manipulate the master. Call blocks until launch is complete

Parameters:

xml (str) - roslaunch XML file to launch

Returns: int, str, [ [str], [str] ]

code, msg, [ [ successful launches], [failed launches] ]
