Detailed Description

template<typename WeightSet, typename RandomGenerator = std::default_random_engine>
class vcsn::detail::random_weight_base< WeightSet, RandomGenerator >

Abstract class for random weight generation.

It contains the parsing of the arguments (which can be overridden), the map of probabilities, the min and the max.
