Detailed Description

Helper class to build a spot::tgba_bdd_concrete object.

Member Function Documentation

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

Add a new constraint to the relation.

int spot::tgba_bdd_concrete_factory::create_anonymous_state ( )

Create a anonymous Now/Next variables.

Returns
The BDD variable number v for the Now state. The Next BDD corresponds to v+1.
int spot::tgba_bdd_concrete_factory::create_atomic_prop ( const ltl::formula f)

Create an atomic proposition variable for formula f.

Parameters
fThe 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().

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

Create a Now/Next variables for formula f.

Parameters
fThe formula to create a state for.
Returns
The BDD variable number v for the Now state. The Next BDD corresponds to v+1.

The state variables are not created if they already exist. Instead their existing variable numbers are 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
ba BDD indicating which variables are in the acceptance set
athe formula associated
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().

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.
