## Member Typedef Documentation

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

The type of the map that stores the predecessor arcs of the DFS 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.

## Member Function Documentation

static PredMap* createPredMap | ( | const Digraph & | g | ) |
| inlinestatic

This function instantiates a PredMap.

Parameters

  g | is the digraph, to which we would like to define the PredMap.

static ProcessedMap* createProcessedMap | ( | const Digraph & | g | ) |
| inlinestatic

This function instantiates a ProcessedMap.

Parameters

  g | is the digraph, to which we would like to define the ProcessedMap.

static ReachedMap* createReachedMap | ( | const Digraph & | g | ) |
| inlinestatic

This function instantiates a ReachedMap.

Parameters

  g | is the digraph, to which we would like to define the ReachedMap.

static DistMap* createDistMap | ( | const Digraph & | g | ) |
| inlinestatic

This function instantiates a DistMap.

Parameters

  g | is the digraph, to which we would like to define the DistMap.
