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.

interactive_markers::InteractiveMarkerServer::~InteractiveMarkerServer (  ) 

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

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 199 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 445 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 191 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 315 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.

Definition at line 307 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 293 of file interactive_marker_server.cpp.

void interactive_markers::InteractiveMarkerServer::keepAlive (  )  [private]

Definition at line 429 of file interactive_marker_server.cpp.

void interactive_markers::InteractiveMarkerServer::processFeedback ( const FeedbackConstPtr feedback  )  [private]

Definition at line 376 of file interactive_marker_server.cpp.

void interactive_markers::InteractiveMarkerServer::publish ( visualization_msgs::InteractiveMarkerUpdate update  )  [private]

Definition at line 437 of file interactive_marker_server.cpp.

void interactive_markers::InteractiveMarkerServer::publishInit (  )  [private]

Definition at line 357 of file interactive_marker_server.cpp.

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.

Definition at line 237 of file interactive_marker_server.cpp.

bool interactive_markers::InteractiveMarkerServer::setPose ( const std::string &  name,
const geometry_msgs::Pose pose,
const std_msgs::Header &  header = std_msgs::Header() 
)

Update the pose of a 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
pose The new pose
header Header replacement. Leave this empty to use the previous one.
