Detailed Description

template<Automaton Aut, typename WeightSet = weightset_t_of<Aut>, bool Deterministic = false, bool AllOut = false, bool KeepTransitions = false>
class vcsn::detail::transition_map< Aut, WeightSet, Deterministic, AllOut, KeepTransitions >

Cache the outgoing transitions of an automaton as efficient maps label -> vector<(weight, dst)>.

Easy to zip.

Template Parameters
AutThe automaton type.
WeightSetThe set of weights into which the weights will be converted.
DeterministicWhether the automaton is guaranteed to be deterministic. If it is, transition_map[state][label] returns a single result, otherwise a vector.
AllOutWhether even the transitions to post() (via the special label) are to be included.
KeepTransitionsIf enabled, add a "transition" field to the cache that allows to recover the transition id.
