Detailed Description

Implement iterator pattern on successor of a state_kripke.

Member Function Documentation

virtual bdd spot::kripke_succ_iterator::current_acceptance_conditions ( ) const
virtualinherited

Get the acceptance conditions on the transition leading to this successor.

Implements spot::tgba_succ_iterator.

virtual bdd spot::kripke_succ_iterator::current_condition ( ) const
virtualinherited

Get the condition on the transition leading to this successor.

This is a boolean function of atomic propositions.

Implements spot::tgba_succ_iterator.

virtual state_kripke* spot::kripke_explicit_succ_iterator::current_state ( ) const
virtual

Get the state of the current successor.

Note that the same state may occur at different points in the iteration. These actually correspond to the same destination. It just means there were several transitions, with different conditions, leading to the same state.

The returned state should be destroyed (see state::destroy) by the caller after it is no longer used.

Implements spot::tgba_succ_iterator.

virtual bool spot::kripke_explicit_succ_iterator::done ( ) const
virtual

Check whether the iteration is finished.

This function should be called after any call to first() or next() and before any enquiry about the current state.

The usual way to do this is with a for loop.

for (s->first(); !s->done(); s->next())
  ...  

Implements spot::tgba_succ_iterator.

virtual void spot::kripke_explicit_succ_iterator::first ( )
virtual

Position the iterator on the first successor (if any).

This method can be called several times to make multiple passes over successors.

Warning
One should always call done() to ensure there is a successor, even after first(). A common trap is to assume that there is at least one successor: this is wrong.

Implements spot::tgba_succ_iterator.

virtual void spot::kripke_explicit_succ_iterator::next ( )
virtual

Jump to the next successor (if any).

Warning
Again, one should always call done() to ensure there is a successor.

Implements spot::tgba_succ_iterator.
