Detailed Description

Acts as a server to one or many GUIs (e.g. rviz) displaying a set of interactive markers

Note: Keep in mind that changes made by calling insert(), erase(), setCallback() etc. are not applied until calling applyChanges().

Constructor & Destructor Documentation

interactive_markers::InteractiveMarkerServer::InteractiveMarkerServer	(	const std::string &	topic_ns,
		const std::string &	server_id = `""`,
		bool	spin_thread = `false`
	)

Parameters

topic_ns	The interface will use the topics topic_ns/update and topic_ns/feedback for communication.
server_id	If you run multiple servers on the same topic from within the same node, you will need to assign different names to them. Otherwise, leave this empty.
spin_thread	If set to true, will spin up a thread for message handling. All callbacks will be called from that thread.

Definition at line 42 of file interactive_marker_server.cpp.

interactive_markers::InteractiveMarkerServer::~InteractiveMarkerServer ( )

Destruction of the interface will lead to all managed markers being cleared.

Definition at line 81 of file interactive_marker_server.cpp.

Member Function Documentation

void interactive_markers::InteractiveMarkerServer::applyChanges ( )

Apply changes made since the last call to this method & broadcast an update to all clients.

Definition at line 110 of file interactive_marker_server.cpp.

void interactive_markers::InteractiveMarkerServer::clear ( )

Clear all markers. Note: This change will not take effect until you call applyChanges().

Definition at line 200 of file interactive_marker_server.cpp.

void interactive_markers::InteractiveMarkerServer::doSetPose	(	M_UpdateContext::iterator	update_it,
		const std::string &	name,
		const geometry_msgs::Pose &	pose,
		const std_msgs::Header &	header
	)

private

Definition at line 474 of file interactive_marker_server.cpp.

bool interactive_markers::InteractiveMarkerServer::empty ( ) const

Return whether the server contains any markers. Note: Does not include markers inserted since the last applyChanges().

Returns: true if the server contains no markers

Definition at line 214 of file interactive_marker_server.cpp.

bool interactive_markers::InteractiveMarkerServer::erase ( const std::string & name )

Erase the marker with the specified name Note: This change will not take effect until you call applyChanges().

Returns: true if a marker with that name exists

Parameters

name	Name of the interactive marker

Definition at line 192 of file interactive_marker_server.cpp.

bool interactive_markers::InteractiveMarkerServer::get	(	std::string	name,
		visualization_msgs::InteractiveMarker &	int_marker
	)		const

Get marker by name

Parameters

	name	Name of the interactive marker
[out]	int_marker	Output message

Returns: true if a marker with that name exists

Definition at line 342 of file interactive_marker_server.cpp.

void interactive_markers::InteractiveMarkerServer::insert ( const visualization_msgs::InteractiveMarker & int_marker )

Add or replace a marker without changing its callback functions. Note: Changes to the marker will not take effect until you call applyChanges(). The callback changes immediately.

Parameters

int_marker The marker to be added or replaced

Definition at line 320 of file interactive_marker_server.cpp.

void interactive_markers::InteractiveMarkerServer::insert	(	const visualization_msgs::InteractiveMarker &	int_marker,
		FeedbackCallback	feedback_cb,
		uint8_t	feedback_type = `DEFAULT_FEEDBACK_CB`
	)

Add or replace a marker and its callback functions Note: Changes to the marker will not take effect until you call applyChanges(). The callback changes immediately.

Parameters

int_marker	The marker to be added or replaced
feedback_cb	Function to call on the arrival of a feedback message.
feedback_type	Type of feedback for which to call the feedback.

bool interactive_markers::InteractiveMarkerServer::setCallback	(	const std::string &	name,
		FeedbackCallback	feedback_cb,
		uint8_t	feedback_type = `DEFAULT_FEEDBACK_CB`
	)

Add or replace a callback function for the specified marker. Note: This change will not take effect until you call applyChanges(). The server will try to call any type-specific callback first. If none is set, it will call the default callback. If a callback for the given type already exists, it will be replaced. To unset a type-specific callback, pass in an empty one.

Parameters

name	Name of the interactive marker
feedback_cb	Function to call on the arrival of a feedback message.
feedback_type	Type of feedback for which to call the feedback. Leave this empty to make this the default callback.
