Method Details

init(self, period, callback, oneshot=False)
(Constructor)

source code

Constructor.

Parameters:

period (rospy.Duration) - desired period between callbacks
callback (function taking rospy.TimerEvent) - callback to be called
oneshot (bool) - if True, fire only once, otherwise fire continuously until shutdown is called [default: False]

Overrides: object.__init__

run(self)

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.
