A state for spot::twa_product.
Definition: twaproduct.hh:33
Abstract class for states.
Definition: twa.hh:47
A lazy product. (States are computed on the fly.)
Definition: tgtaproduct.hh:32
virtual twa_succ_iterator * succ_iter(const state *local_state) const override
Get an iterator over the successors of local_state.
virtual const state * get_init_state() const override
Get the initial state of the automaton.
Iterate over the successors of a product computed on the fly.
Definition: tgtaproduct.hh:51
bool done() const override
Check whether the iteration is finished.
bdd cond() const override
Get the condition on the edge leading to this successor.
acc_cond::mark_t acc() const override
Get the acceptance mark of the edge leading to this successor.
bool next() override
Jump to the next successor (if any).
state_product * dst() const override
Get the destination state of the current edge.
bool first() override
Position the iterator on the first successor (if any).
A Transition-based Generalized Testing Automaton (TGTA).
