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

Aut	The automaton type.
WeightSet	The set of weights into which the weights will be converted.
Deterministic	Whether the automaton is guaranteed to be deterministic. If it is, transition_map[state][label] returns a single result, otherwise a vector.
AllOut	Whether even the transitions to post() (via the special label) are to be included.
KeepTransitions	If enabled, add a "transition" field to the cache that allows to recover the transition id.
