Member Function Documentation

◆ as_ast()

def as_ast (   self)
Return a pointer to the corresponding C Z3_ast object.

Reimplemented from ExprRef.

Definition at line 1926 of file z3py.py.

1926  def as_ast(self):
1927  return Z3_pattern_to_ast(self.ctx_ref(), self.ast)
Z3_ast Z3_API Z3_pattern_to_ast(Z3_context c, Z3_pattern p)
Convert a Z3_pattern into Z3_ast. This is just type casting.

◆ get_id()

def get_id (   self)
Return unique identifier for object. It can be used for hash-tables and maps.

Reimplemented from ExprRef.

Definition at line 1929 of file z3py.py.

1929  def get_id(self):
1930  return Z3_get_ast_id(self.ctx_ref(), self.as_ast())
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....
