MapToFunctor< M > Class Template Reference

Detailed Description

template<typename M>
class lemon::MapToFunctor< M >

This class converts a map to an STL style (unary) functor. That is it provides an operator() to read its values.

For the sake of convenience it also works as a usual readable map, i.e. operator[] and the Key and Value typedefs also exist.

The simplest way of using this map is through the mapToFunctor() function.
