Constructor & Destructor Documentation

template<Automaton Aut>

vcsn::detail::delgado_profiler< Aut >::delgado_profiler ( const automaton_t &  aut, bool  count_labels = false  )

inline

Build a generator of Delgado-Morais state profiles.

Parameters

aut	the input automaton
count_labels	whether we use the width of the expressions, instead of the length.

Definition at line 109 of file to-expression.hh.

template<Automaton Aut>

void vcsn::detail::delgado_profiler< Aut >::invalidate_cache ( transition_t  t )

inline

Updating transitions' size in the cache during the profiler's construction would be clearer but appear to be less efficient.

Invalidate Update 0.29s 0.37s : a.expression(linear, delgado) # a = std([a-d]?{15})

template<Automaton Aut>

size_t vcsn::detail::delgado_profiler< Aut >::size_of_transition ( transition_t  t )

inline

The "weight" of a transition.

That is to say, the size of its expression.

template<Automaton Aut>

void vcsn::detail::delgado_profiler< Aut >::update ( state_profile &  p )

inline

The "weight" of a state, as defined by Delgado-Morais.

We use the word "size" instead, since "weight" has already a strong meaning in Vcsn...
