Build a spot::tgba_succ_iterator_concrete.
successors | The set of successors with ingoing conditions and acceptance conditions, represented as a BDD. The job of this iterator will be to enumerate the satisfactions of that BDD and split them into destination states and conditions, and compute acceptance conditions. |
d | The core data of the automata. These contains sets of variables useful to split a BDD, and compute acceptance conditions. |

Get the acceptance conditions on the transition leading to this successor.
Implements spot::tgba_succ_iterator.
|
virtual |
Get the condition on the transition leading to this successor.
This is a boolean function of atomic propositions.
Implements spot::tgba_succ_iterator.
|
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 |
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 |
Position the iterator on the first successor (if any).
This method can be called several times to make multiple passes over successors.
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 |
Jump to the next successor (if any).
done()
to ensure there is a successor. Implements spot::tgba_succ_iterator.
