Member Typedef Documentation

typedef Digraph::template NodeMap<typename Digraph::Arc> PredMap

The type of the map that stores the predecessor arcs of the shortest paths. It must conform to the WriteMap concept.

typedef NullMap<typename Digraph::Node,bool> ProcessedMap

The type of the map that indicates which nodes are processed. It must conform to the WriteMap concept. By default, it is a NullMap.

typedef Digraph::template NodeMap<bool> ReachedMap

The type of the map that indicates which nodes are reached. It must conform to the ReadWriteMap concept.

typedef Digraph::template NodeMap<int> DistMap

The type of the map that stores the distances of the nodes. It must conform to the WriteMap concept.
