Instance Variables

update_signal(...)
update_signal is a signal, which is emitted, if a new master_discovery_fkie.MasterInfo is retrieved.

source code

master_errors_signal(...)
master_errors_signal is a signal (masteruri, list of errors), which is emitted, if we get a list with errors from remote master_discovery.

source code

error_signal(...)
error_signal is a signal (masteruri, error message), which is emitted, if an error while retrieving a master info was occurred.

source code

timediff_signal(...)
timediff_signal is a signal (masteruri, time difference), which is emitted after the difference of time to the remote host is determined.

Method Details

init(self, monitoruri, masteruri, delayed_exec=0.0, parent=None)
(Constructor)

source code

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

Parameters:

masteruri (str) - the URI of the remote ROS master
monitoruri (str) - the URI of the monitor RPC interface of the master_discovery node
delayed_exec (float) - Delay the execution of the request for given seconds.

Overrides: object.__init__

run(self)

source code

Method representing the thread's activity.

You may override this method in a subclass. The standard run() method invokes the callable object passed to the object's constructor as the target argument, if any, with sequential and keyword arguments taken from the args and kwargs arguments, respectively.

Overrides: threading.Thread.run
