Protected member functions¶
-
std::set<propositional_variable>
compute_declared_variables() const¶ Returns the predicate variables appearing in the left hand side of an equation.
Returns: The predicate variables appearing in the left hand side of an equation.
-
bool
is_declared_in(Iter first, Iter last, const propositional_variable_instantiation &v, const data::data_specification &data_spec) const¶ Checks if the propositional variable instantiation v appears with the right type in the sequence of propositional variable declarations [first, last).
Parameters:
- first Start of a sequence of propositional variable declarations
- last End of a sequence of propositional variable declarations
- v A propositional variable instantation
- data_spec A data specification.
Returns: True if the type of v is matched correctly
Parameters:

Public member functions¶
-
std::set<propositional_variable>
binding_variables() const Returns the set of binding variables of the pbes. This is the set variables that occur on the left hand side of an equation.
Returns: The set of binding variables of the pbes.
-
data::data_specification &
data() Returns the data specification.
Returns: The data specification of the pbes
-
const data::data_specification &
data() const Returns the data specification.
Returns: The data specification of the pbes
-
std::vector<pbes_equation> &
equations() Returns the equations.
Returns: The equations.
-
const std::vector<pbes_equation> &
equations() const Returns the equations.
Returns: The equations.
-
std::set<data::variable> &
global_variables() Returns the declared free variables of the pbes.
Returns: The declared free variables of the pbes.
-
const std::set<data::variable> &
global_variables() const Returns the declared free variables of the pbes.
Returns: The declared free variables of the pbes.
-
propositional_variable_instantiation &
initial_state() Returns the initial state.
Returns: The initial state.
-
const propositional_variable_instantiation &
initial_state() const Returns the initial state.
Returns: The initial state.
-
bool
is_closed() const True if the pbes is closed.
Returns: Returns true if all occurring variables are binding variables, and the initial state variable is a binding variable.
-
bool
is_well_typed() const Checks if the PBES is well typed.
Returns: True if the sorts occurring in the free variables of the equations are declared in the data specification the sorts occurring in the binding variable parameters are declared in the data specification the sorts occurring in the quantifier variables of the equations are declared in the data specification the binding variables of the equations have unique names (well formedness) the global variables occurring in the equations are declared in global_variables()the global variables occurring in the equations with the same name are identical the declared global variables and the quantifier variables occurring in the equations have different names the predicate variable instantiations occurring in the equations match with their declarations the predicate variable instantiation occurring in the initial state matches with the declaration the data specification is well typed
N.B. Conflicts between the types of instantiations and declarations of binding variables are not checked!
-
std::set<propositional_variable_instantiation>

-
std::set<propositional_variable>
occurring_variables() const Returns the set of occurring propositional variable declarations of the pbes, i.e. the propositional variable declarations that occur in the right hand side of an equation.
Returns: The occurring propositional variable declarations of the pbes
