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.

Constructor & Destructor Documentation

◆ Updater()

diagnostic_updater::Updater::Updater	(	ros::NodeHandle	h = `ros::NodeHandle()`,
		ros::NodeHandle	ph = `ros::NodeHandle("~")`,
		std::string	node_name = `ros::this_node::getName()`
	)

inline

Constructs an updater class.

Parameters

h	Node handle from which to get the diagnostic_period parameter.

Definition at line 374 of file diagnostic_updater.h.

Member Function Documentation

◆ addedTaskCallback()

virtual void diagnostic_updater::Updater::addedTaskCallback ( DiagnosticTaskInternal & task )

inlineprivatevirtual

Causes a placeholder DiagnosticStatus to be published as soon as a diagnostic task is added to the Updater.

Reimplemented from diagnostic_updater::DiagnosticTaskVector.

Definition at line 570 of file diagnostic_updater.h.

◆ broadcast()

void diagnostic_updater::Updater::broadcast	(	int	lvl,
		const std::string	msg
	)

inline

Output a message on all the known DiagnosticStatus.

Useful if something drastic is happening such as shutdown or a self-test.

Parameters

lvl	Level of the diagnostic being output.
msg	Status message to output.

Definition at line 477 of file diagnostic_updater.h.

◆ force_update()

void diagnostic_updater::Updater::force_update ( )

inline

Forces the diagnostics to update.

Useful if the node has undergone a drastic state change that should be published immediately.

Definition at line 400 of file diagnostic_updater.h.

◆ getPeriod()

double diagnostic_updater::Updater::getPeriod ( )

inline

Returns the interval between updates.

Definition at line 449 of file diagnostic_updater.h.

◆ publish() [1/2]

void diagnostic_updater::Updater::publish ( diagnostic_msgs::DiagnosticStatus & stat )

inlineprivate

Publishes a single diagnostic status.

Definition at line 527 of file diagnostic_updater.h.

◆ publish() [2/2]

void diagnostic_updater::Updater::publish ( std::vector< diagnostic_msgs::DiagnosticStatus > & status_vec )

inlineprivate

Publishes a vector of diagnostic statuses.

Definition at line 537 of file diagnostic_updater.h.

◆ setHardwareID()

void diagnostic_updater::Updater::setHardwareID ( const std::string & hwid )

inline

Definition at line 507 of file diagnostic_updater.h.

◆ setHardwareIDf()

void diagnostic_updater::Updater::setHardwareIDf	(	const char *	format,
			...
	)

inline

Definition at line 496 of file diagnostic_updater.h.

◆ setup()

void diagnostic_updater::Updater::setup ( )

inlineprivate

Publishes on /diagnostics and reads the diagnostic_period parameter.

Definition at line 554 of file diagnostic_updater.h.

◆ update()

void diagnostic_updater::Updater::update ( )

inline

Causes the diagnostics to update if the inter-update interval has been exceeded.

Definition at line 383 of file diagnostic_updater.h.

◆ update_diagnostic_period()

void diagnostic_updater::Updater::update_diagnostic_period ( )

inlineprivate

Recheck the diagnostic_period on the parameter server. (Cached)

Definition at line 517 of file diagnostic_updater.h.
