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.
