costmap_2d::Costmap2DPublisher::Costmap2DPublisher	(	ros::NodeHandle	ros_node,
		double	publish_frequency,
		std::string	global_frame
	)

Constructor for the Costmap2DPublisher.

Parameters:

	ros_node	The node under which to publish the visualization output
	global_frame	The frame in which to publish the visualization output

Definition at line 40 of file costmap_2d_publisher.cpp.

costmap_2d::Costmap2DPublisher::~Costmap2DPublisher ( )

Destructor.

Definition at line 51 of file costmap_2d_publisher.cpp.

bool costmap_2d::Costmap2DPublisher::active ( ) [inline]

Check if the publisher is active.

Returns:: True if the frequency for the publisher is non-zero, false otherwise
