Detailed Description

A Sort is essentially a type. Every Z3 expression has a sort. A sort is an AST node.

as_ast()

as_ast

(

self

)

Return a pointer to the corresponding C Z3_ast object.

Reimplemented from AstRef.

Definition at line 593 of file z3py.py.

    def as_ast(self):
        # Z3_sort_to_ast is only a pointer cast, so do it here instead of calling into Z3.

cast()

cast	(		self,
			val )

Try to cast `val` as an element of sort `self`.

This method is used in Z3Py to convert Python objects such as integers,
floats, longs and strings into Z3 expressions.

>>> x = Int('x')
>>> RealSort().cast(x)

kind()

kind

(

This method can be used to test if `self` is one of the Z3 builtin sorts.
