Constructor & Destructor Documentation

DriveParametersSource::DriveParametersSource	(	ros::NodeHandle *	node_handle,
		const char *	topic,
		DriveParameterCallbackFunction	update_callback,
		DriveMode	drive_mode,
		ros::Duration	timeout
	)

Construct a new DriveParametersSource object, subscribes to the topic and stores the parameters into local variables.

Parameters

node_handle	A node handle is needed to create a topic subscriber
topic	The name of the drive_param topic to subscribe to
update_callback	Callback function that will be called whenever a message was received
priority	Priority of the source. If multiple sources are not idle, the source with the highest priority is forwarded.
timeout	Messages will be deferred when they are older than this, in seconds.
