Detailed Description

Manages a list of diagnostic tasks, and calls them in a rate-limited manner.

This class manages a list of diagnostic tasks. Its update function
should be called frequently. At some predetermined rate, the update
function will cause all the diagnostic tasks to run, and will collate
and publish the resulting diagnostics. The publication rate is
determined by the "~diagnostic_period" ros parameter.

The class also allows an update to be forced when something significant
has happened, and allows a single message to be broadcast on all the
diagnostics if normal operation of the node is suspended for some
reason.

			msg
	)

Publishes a single diagnostic status or a vector of diagnostic statuses.

Definition at line 323 of file _diagnostic_updater.py.

def diagnostic_updater._diagnostic_updater.Updater.setHardwareID	(		self,
