Detailed Description

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

◆ as_ast()

◆ 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)
ToReal(x)

Reimplemented in ArithSortRef, BitVecSortRef, BoolSortRef, FPSortRef, and TypeVarRef.

◆ get_id()

get_id ( self)

unsigned Z3_API Z3_get_ast_id(Z3_context c, Z3_ast t)
Return a unique identifier for t. The identifier is unique up to structural equality....

◆ kind()

kind ( self)
Return the Z3 internal kind of a sort.
This method can be used to test if `self` is one of the Z3 builtin sorts.

>>> b = BoolSort()

True
>>> b.kind() == Z3_INT_SORT
False
