Method	`__init__`	Undocumented

def __init__(self, errors, line=-1, override_column=-1, assume_str_is_unicode=True, is_evaluated=True): (source)

Undocumented

Parameters
errors:`Optional[Errors]`	Undocumented
line:`int`	Undocumented
override_column:`int`	Undocumented
assume_str_is_unicode:`bool`	Undocumented
is_evaluated:`bool`	Undocumented

def convert_column(self, column): (source)

Apply column override if defined; otherwise return column.

Column numbers are sometimes incorrect in the AST and the column override can be used to work around that.

Parameters
column:`int`	Undocumented
Returns
`int`	Undocumented

def fail(self, msg, line, column): (source)

Undocumented

Parameters
msg:`str`	Undocumented
line:`int`	Undocumented
column:`int`	Undocumented

def invalid_type(self, node, note=None): (source)

Constructs a type representing some expression that normally forms an invalid type. For example, if we see a type hint that says "3 + 4", we would transform that expression into a RawExpressionType.

The semantic analysis layer will report an "Invalid type" error when it encounters this type, along with the given note if one is provided.

See RawExpressionType's docstring for more details on how it's used.

Parameters
node:`AST`	Undocumented
note:`Optional[str]`	Undocumented
Returns
`RawExpressionType`	Undocumented

def note(self, msg, line, column): (source)

Undocumented

Parameters
msg:`str`	Undocumented
line:`int`	Undocumented
column:`int`	Undocumented

def numeric_type(self, value, n): (source)

Undocumented

Parameters
value:`object`	Undocumented
n:`AST`	Undocumented
Returns
`Type`	Undocumented

def parent(self): (source)

Return the AST node above the one we are processing

Returns
`Optional[AST]`	Undocumented

def translate_argument_list(self, l): (source)

Undocumented

Parameters
l:`Sequence[ast3.expr]`	Undocumented
Returns
`TypeList`	Undocumented

def translate_expr_list(self, l): (source)

Undocumented

Parameters
l:`Sequence[ast3.expr]`	Undocumented
Returns
`List[Type]`	Undocumented

def visit(self, node): (source)
