Helper class for declaring Z3 datatypes. >>> List = Datatype('List') >>> List.declare('cons', ('car', IntSort()), ('cdr', List)) >>> List.declare('nil') >>> List = List.create() >>> # List is now a Z3 declaration >>> List.nil nil >>> List.cons(10, List.nil) cons(10, nil) >>> List.cons(10, List.nil).sort() List >>> cons = List.cons >>> nil = List.nil >>> car = List.car >>> cdr = List.cdr >>> n = cons(1, cons(0, nil)) >>> n cons(1, cons(0, nil)) >>> simplify(cdr(n)) cons(0, nil) >>> simplify(car(n)) 1

Create a Z3 datatype based on the constructors declared using the method `declare()`. The function `CreateDatatypes()` must be used to define mutually recursive datatypes. >>> List = Datatype('List') >>> List.declare('cons', ('car', IntSort()), ('cdr', List)) >>> List.declare('nil') >>> List = List.create() >>> List.nil nil >>> List.cons(10, List.nil) cons(10, nil)

Declare constructor named `name` with the given accessors `args`. Each accessor is a pair `(name, sort)`, where `name` is a string and `sort` a Z3 sort or a reference to the datatypes being declared. In the following example `List.declare('cons', ('car', IntSort()), ('cdr', List))` declares the constructor named `cons` that builds a new List using an integer and a List. It also declares the accessors `car` and `cdr`. The accessor `car` extracts the integer of a `cons` cell, and `cdr` the list of a `cons` cell. After all constructors were declared, we use the method create() to create the actual datatype in Z3. >>> List = Datatype('List') >>> List.declare('cons', ('car', IntSort()), ('cdr', List)) >>> List.declare('nil') >>> List = List.create()
