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 meet the WriteMap concept.

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

The type of the map that indicates which nodes are processed. It must meet 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 meet the ReadWriteMap concept.

typedef Digraph::template NodeMap<int> DistMap

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

The type of the shortest paths. It must meet the Path concept.
