realtime_tools::RealtimePublisher< Msg >::RealtimePublisher	(	const ros::NodeHandle &	node,
		const std::string &	topic,
		int	queue_size,
		bool	latched = `false`

inline

Constructor for the realtime publisher.

Parameters

node	the nodehandle that specifies the namespace (or prefix) that is used to advertise the ROS topic
topic	the topic name to advertise
queue_size	the size of the outgoing ROS buffer
latched	. optional argument (defaults to false) to specify is publisher is latched or not

◆ lock()

template<class Msg>

void realtime_tools::RealtimePublisher< Msg >::lock ( )

inline

Get the data lock form non-realtime.

To publish data from the realtime loop, you need to run trylock to attempt to get unique access to the msg_ variable. Trylock returns true if the lock was aquired, and false if it failed to get the lock.

◆ stop()

template<class Msg>

void realtime_tools::RealtimePublisher< Msg >::stop ( )

inline

Stop the realtime publisher from sending out more ROS messages.

Definition at line 101 of file realtime_publisher.h.

◆ trylock()

template<class Msg>

bool realtime_tools::RealtimePublisher< Msg >::trylock ( )

inline

Try to get the data lock from realtime.

To publish data from the realtime loop, you need to run trylock to attempt to get unique access to the msg_ variable. Trylock returns true if the lock was aquired, and false if it failed to get the lock.

Definition at line 115 of file realtime_publisher.h.

◆ unlock()

template<class Msg>

void realtime_tools::RealtimePublisher< Msg >::unlock ( )

inline

Unlocks the data without publishing anything.

Definition at line 172 of file realtime_publisher.h.

◆ unlockAndPublish()

template<class Msg>

void realtime_tools::RealtimePublisher< Msg >::unlockAndPublish ( )

inline

Unlock the msg_ variable.

After a successful trylock and after the data is written to the mgs_ variable, the lock has to be released for the message to get published on the specified topic.
