Member Function Documentation

bdd spot::ta_succ_iterator_product::current_acceptance_conditions ( ) const
virtualinherited

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

Implements spot::ta_succ_iterator.

bdd spot::ta_succ_iterator_product::current_condition ( ) const
virtualinherited

Get the changeset on the transition leading to current successor.

This is a boolean function of atomic propositions.

Implements spot::ta_succ_iterator.

state_ta_product* spot::ta_succ_iterator_product::current_state ( ) const
virtualinherited

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::ta_succ_iterator.

bool spot::ta_succ_iterator_product::done ( ) const
virtualinherited

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::ta_succ_iterator.

void spot::ta_succ_iterator_product::first ( )
virtualinherited

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::ta_succ_iterator.

bool spot::ta_succ_iterator_product::is_stuttering_transition ( ) const
inherited

Return true if the changeset of the current transition is empty.

void spot::ta_succ_iterator_product::next ( )
virtualinherited

Jump to the next successor (if any).

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

Implements spot::ta_succ_iterator.

void spot::ta_succ_iterator_product_by_changeset::next_kripke_dest ( )

Move to the next successor in the Kripke structure.

void spot::ta_succ_iterator_product::step_ ( )
protectedinherited

Internal routines to advance to the next successor.
