Public Member Functions inherited from costmap_converter::CostmapToPolygonsDBSMCCH | |
virtual void | compute () |
This method performs the actual work (conversion of the costmap to polygons) More... | |
CostmapToPolygonsDBSMCCH () | |
Constructor. More... | |
PolygonContainerConstPtr | getPolygons () |
Get a shared instance of the current polygon container. More... | |
virtual void | initialize (ros::NodeHandle nh) |
Initialize the plugin. More... | |
virtual void | setCostmap2D (costmap_2d::Costmap2D *costmap) |
Pass a pointer to the costap to the plugin. More... | |
virtual void | updateCostmap2D () |
Get updated data from the previously set Costmap2D. More... | |
virtual | ~CostmapToPolygonsDBSMCCH () |
Destructor. More... | |
Public Member Functions inherited from costmap_converter::BaseCostmapToPolygons | |
virtual ObstacleArrayConstPtr | getObstacles () |
Get a shared instance of the current obstacle container If this method is not overwritten by the underlying plugin, the obstacle container just imports getPolygons(). More... | |
virtual void | setOdomTopic (const std::string &odom_topic) |
Set name of robot's odometry topic. More... | |
virtual bool | stackedCostmapConversion () |
Determines whether an additional plugin for subsequent costmap conversion is specified. More... | |
void | startWorker (ros::Rate rate, costmap_2d::Costmap2D *costmap, bool spin_thread=false) |
Instantiate a worker that repeatedly coverts the most recent costmap to polygons. The worker is implemented as a timer event that is invoked at a specific rate . The passed costmap pointer must be valid at the complete time and must be lockable. By specifying the argument spin_thread the timer event is invoked in a separate thread and callback queue or otherwise it is called from the global callback queue (of the node in which the plugin is used). More... | |
void | stopWorker () |
Stop the worker that repeatedly converts the costmap to polygons. More... | |
virtual | ~BaseCostmapToPolygons () |
Destructor. More... | |
