MRPT
2.0.1
|
A directed graph with the argument of the template specifying the type of the annotations in the edges.
This class only keeps a list of edges (in the member edges), so there is no information stored for each node but its existence referred by a node_ID.
Note that edges are stored as a std::multimap<> to allow multiple edges between the same pair of nodes.
