Detailed Description

template<typename Map>
class rndm::NuRandomServiceHelper::MapKeyConstIteratorBox< Map >

Provides iterators for std::begin() and std::end()

Template Parameters

Map	type of the map to be wrapped

This object can wrap a map-like type to iterate through its key in a range-based for loop.

Example of usage:

std::map<int, double> my_map;
// ... fill the map ...
// print all the kets
for (int const& key: MapKeyConstIteratorBox<std::map<int, double>>(my_map))
  std::cout << "Key: " << key << std::endl;

Only constant iteration on keys is provided.
