Constructor & Destructor Documentation

nav2_route::GraphLoader::GraphLoader	(	nav2_util::LifecycleNode::SharedPtr	node,
		std::shared_ptr< tf2_ros::Buffer >	tf,
		const std::string	frame
	)

explicit

Parameters

options Additional options to control creation of the node.

Definition at line 23 of file graph_loader.cpp.

bool nav2_route::GraphLoader::loadGraphFromFile	(	Graph &	graph,
		GraphToIDMap &	idx_map,
		const std::string &	filepath
	)

Loads a graph object with file information from a filepath.

Parameters

graph	Graph to populate
idx_map	A map translating nodeid's to graph idxs for use in graph modification services and idx-based route planning requests. This is much faster than using a map the full graph data structure.
filepath	The filepath to the graph data
graph_file_loader_id	The id of the GraphFileLoader

Definition at line 64 of file graph_loader.cpp.

Here is the call graph for this function:

bool nav2_route::GraphLoader::loadGraphFromParameter	(	Graph &	graph,
		GraphToIDMap &	idx_map
	)

Loads a graph object with file information from ROS parameter, if provided.

Parameters

graph	Graph to populate
idx_map	A map translating nodeid's to graph idxs for use in graph modification services and idx-based route planning requests. This is much faster than using a map the full graph data structure.
graph_file_loader_id	The id of the GraphFileLoader
