BfsWizard< TR > Class Template Reference

Detailed Description

template<class TR>
class lemon::BfsWizard< TR >

This class is created to make it easier to use Bfs algorithm. It uses the functions and features of the plain Bfs, but it is much simpler to use it.

Simplicity means that the way to change the types defined in the traits class is based on functions that returns the new class and not on templatable built-in classes. When using the plain Bfs the new class with the modified type comes from the original class by using the :: operator. In the case of BfsWizard only a function have to be called and it will return the needed class.

It does not have own run method. When its run method is called it initiates a plain Bfs class, and calls the Bfs::run method of it. #include <lemon/bfs.h>
