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.


Constructor & Destructor Documentation

spot::emptiness_check_result::emptiness_check_result const tgba a  )  [inline]
 


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.

const tgba* spot::emptiness_check_result::automaton  )  const [inline]
 

The automaton on which an accepting_run() was found.
