Member Function Documentation

int spot::tgba_bdd_concrete_factory::create_state ( const ltl::formula * f )

Create a state variable for formula f.

Parameters:

The formula to create a state for.

Returns:: The variable number for this state.

The state is not created if it already exists. Instead its existing variable number is returned. Variable numbers can be turned into BDD using ithvar().

int spot::tgba_bdd_concrete_factory::create_atomic_prop ( const ltl::formula * f )

Create an atomic proposition variable for formula f.

Parameters:

The formula to create an aotmic proposition for.

Returns:: The variable number for this state.

The atomic proposition is not created if it already exists. Instead its existing variable number is returned. Variable numbers can be turned into BDD using ithvar().

void spot::tgba_bdd_concrete_factory::declare_acceptance_condition	(	bdd	b,
		const ltl::formula *	a
	)

Declare an acceptance condition.

Formula such as 'f U g' or 'F g' make the promise that 'g' will be fulfilled eventually. So once one of this formula has been translated into a BDD, we use declare_acceptance_condition() to associate all other states to the acceptance set of 'g'.

Parameters:

	b	a BDD indicating which variables are in the acceptance set
	a	the formula associated

const tgba_bdd_core_data& spot::tgba_bdd_concrete_factory::get_core_data ( ) const [virtual]

Get the core data for the new automata.

Implements spot::tgba_bdd_factory.

bdd_dict* spot::tgba_bdd_concrete_factory::get_dict ( ) const

void spot::tgba_bdd_concrete_factory::constrain_relation ( bdd new_rel )

Add a new constraint to the relation.

void spot::tgba_bdd_concrete_factory::finish ( )

Perfom final computations before the relation can be used.

This function should be called after all propositions, state, acceptance conditions, and constraints have been declared, and before calling get_code_data() or get_dict().
