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>

Constructor & Destructor Documentation

DfsWizard ( const Digraph g) [inline]

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

Parameters:
gThe 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.
