Public Member Functions
virtual	~prop_convt ()

virtual literalt	convert (const exprt &expr)=0
	Convert a Boolean expression and return the corresponding literal. More...

virtual tvt	l_get (literalt l) const =0
	Return value of literal `l` from satisfying assignment. More...

Public Member Functions inherited from stack_decision_proceduret
virtual void	push (const std::vector< exprt > &assumptions)=0
	Pushes a new context on the stack that consists of the given (possibly empty vector of) `assumptions`. More...

virtual void	push ()=0
	Push a new context on the stack This context becomes a child context nested in the current context. More...

virtual void	pop ()=0
	Pop whatever is on top of the stack. More...

virtual	~stack_decision_proceduret ()=default

Public Member Functions inherited from decision_proceduret
virtual void	set_to (const exprt &, bool value)=0
	For a Boolean expression `expr`, add the constraint 'expr' if `value` is `true`, otherwise add 'not expr'. More...

void	set_to_true (const exprt &)
	For a Boolean expression `expr`, add the constraint 'expr'. More...

void	set_to_false (const exprt &)
	For a Boolean expression `expr`, add the constraint 'not expr'. More...

virtual exprt	handle (const exprt &)=0
	Generate a handle, which is an expression that has the same value as the argument in any model that is generated; this offers an efficient way to refer to the expression in subsequent calls to get or set_to. More...

resultt	operator() ()
	Run the decision procedure to solve the problem This corresponds to SMT-LIB's check-sat. More...

resultt	operator() (const exprt &assumption)
	Run the decision procedure to solve the problem under the given assumption. More...

virtual exprt	get (const exprt &) const =0
	Return `expr` with variables replaced by values from satisfying assignment if available. More...

virtual void	print_assignment (std::ostream &out) const =0
	Print satisfying assignment to `out`. More...

virtual std::string	decision_procedure_text () const =0
	Return a textual description of the decision procedure. More...

virtual std::size_t	get_number_of_solver_calls () const =0
	Return the number of incremental solver calls. More...

virtual	~decision_proceduret ()

Additional Inherited Members
Public Types inherited from decision_proceduret
