Detailed Description

The result of an emptiness check.

Instances of these class should not last longer than the instances of emptiness_check that produced them as they may reference data internal to the check.

Member Function Documentation

virtual tgba_run* spot::emptiness_check_result::accepting_run  )  [virtual]
 

Return a run accepted by the automata passed to the emptiness check.

This method might actually compute the acceptance run. (Not all emptiness check algorithms actually produce a counter-example as a side-effect of checking emptiness, some need some post-processing.)

This can also return 0 if the emptiness check algorithm cannot produce a counter example (that does not mean there is no counter-example; the mere existence of an instance of this class asserts the existence of a counter-example).

Reimplemented in spot::couvreur99_check_result.

The automaton on which an accepting_run() was found.

const option_map& spot::emptiness_check_result::options  )  const [inline]
 

Return the options parametrizing how the accepting run is computed.

virtual void spot::emptiness_check_result::options_updated const option_map old  )  [protected, virtual]
 

Notify option updates.

const char* spot::emptiness_check_result::parse_options char *  options  ) 
 

Modify the algorithm options.

virtual const unsigned_statistics* spot::emptiness_check_result::statistics  )  const [virtual]
 

Return statistics, if available.
