DfsWizard< TR > Class Template Reference

Detailed Description

template<class TR>
class lemon::DfsWizard< TR >

This auxiliary class is created to implement the function-type interface of Dfs algorithm. It does not have own run() method, it uses the functions and features of the plain Dfs.

This class should only be used through the dfs() function, which makes it easier to use the algorithm.

#include <lemon/dfs.h>

Inherits TR.

Constructor & Destructor Documentation

DfsWizard ( const Digraph &  g )

inline

Constructor that requires parameters. These parameters will be the default values for the traits class.

Parameters

g	The digraph the algorithm runs on.

Member Function Documentation

void run ( Node  s )

inline

This method runs DFS algorithm from node s in order to compute the DFS path to each node.

bool run ( Node  s, Node  t  )

inline

This method runs DFS algorithm from node s in order to compute the DFS path to node t (it stops searching when t is processed).

Returns

true if t is reachable form s.

void run ( )

inline

This method runs DFS algorithm in order to compute the DFS path to each node.

DfsWizard<SetPredMapBase<T> > predMap ( const T &  t )

inline

Named parameter for setting PredMap object.

DfsWizard<SetReachedMapBase<T> > reachedMap ( const T &  t )

inline

Named parameter for setting ReachedMap object.

DfsWizard<SetDistMapBase<T> > distMap ( const T &  t )

inline

Named parameter for setting DistMap object.

DfsWizard<SetProcessedMapBase<T> > processedMap ( const T &  t )

inline

Named parameter for setting ProcessedMap object.

DfsWizard<SetPathBase<T> > path ( const T &  t )

inline

Named parameter for getting the DFS path to the target node.

DfsWizard dist ( const int &  d )

inline

Named parameter for getting the distance of the target node.
