Member Function Documentation

template<typename State>
virtual bdd spot::tgba_explicit_succ_iterator< State >::current_acceptance_conditions ( ) const
inlinevirtual

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

Implements spot::tgba_succ_iterator.

References spot::tgba_explicit_succ_iterator< State >::done(), and spot::tgba_explicit_succ_iterator< State >::it_.

template<typename State>
virtual bdd spot::tgba_explicit_succ_iterator< State >::current_condition ( ) const
inlinevirtual

Get the condition on the transition leading to this successor.

This is a boolean function of atomic propositions.

Implements spot::tgba_succ_iterator.

References spot::tgba_explicit_succ_iterator< State >::done(), and spot::tgba_explicit_succ_iterator< State >::it_.

template<typename State>
virtual State* spot::tgba_explicit_succ_iterator< State >::current_state ( ) const
inlinevirtual

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.

References spot::tgba_explicit_succ_iterator< State >::done(), down_cast, and spot::tgba_explicit_succ_iterator< State >::it_.

template<typename State>
virtual bool spot::tgba_explicit_succ_iterator< State >::done ( ) const
inlinevirtual

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.

References spot::tgba_explicit_succ_iterator< State >::it_, and spot::tgba_explicit_succ_iterator< State >::start_.

Referenced by spot::tgba_explicit_succ_iterator< State >::current_acceptance_conditions(), spot::tgba_explicit_succ_iterator< State >::current_condition(), and spot::tgba_explicit_succ_iterator< State >::current_state().

template<typename State>
virtual void spot::tgba_explicit_succ_iterator< State >::first ( )
inlinevirtual

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.

References spot::tgba_explicit_succ_iterator< State >::it_, and spot::tgba_explicit_succ_iterator< State >::start_.

template<typename State>
State::transitions_t::const_iterator spot::tgba_explicit_succ_iterator< State >::get_iterator ( ) const
inline
template<typename State>
virtual void spot::tgba_explicit_succ_iterator< State >::next ( )
inlinevirtual

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.
