Preflow< GR, CAP, TR >::SetStandardElevator< T > Struct Template Reference

## Detailed Description

### template<typename GR, typename CAP, typename TR>
template<typename T>
struct lemon::Preflow< GR, CAP, TR >::SetStandardElevator< T >

Named parameter for setting Elevator type with automatic allocation. The Elevator should have standard constructor interface to be able to automatically created by the algorithm (i.e. the digraph and the maximum level should be passed to it). However, an external elevator object could also be passed to the algorithm with the elevator() function before calling run() or init().
