FunctorToMap< F, K, V > Class Template Reference


Detailed Description

template<typename F, typename K = typename F::argument_type, typename V = typename F::result_type>
class lemon::FunctorToMap< F, K, V >

This read-only map returns the value of a given functor. Actually, it just wraps the functor and provides the Key and Value typedefs.

Template parameters K and V will become its Key and Value. In most cases they have to be given explicitly because a functor typically does not provide argument_type and result_type typedefs. Parameter F is the type of the used functor.

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