pytype.pytd.visitors.FillInLocalPointers

class documentation

class FillInLocalPointers(Visitor): (source)

Fill in ClassType pointers using symbol tables. This is an in-place visitor! It modifies the original tree. This is necessary because we introduce loops.

Method	`__init__`	Create this visitor.
Method	`EnterClassType`	Fills in a class type.
Method	`_Lookup`	Look up a node by name.
Instance Variable	`_lookup_map`	Undocumented

Inherited from Visitor:

def __init__(self, lookup_map, fallback=None): (source) ¶

overrides pytype.pytd.base_visitor.Visitor.__init__

Create this visitor. You're expected to then pass this instance to node.Visit(). Args: lookup_map: A map from names to symbol tables (i.e., objects that have a "Lookup" function). fallback: A symbol table to be tried if lookup otherwise fails.

def EnterClassType(self, node): (source) ¶

Fills in a class type. Args: node: A ClassType. This node will have a name, which we use for lookup. Returns: The same ClassType. We will have done our best to fill in its "cls" attribute. Call VerifyLookup() on your tree if you want to be sure that all of the cls pointers have been filled in.

def _Lookup(self, node): (source) ¶

Look up a node by name.

_lookup_map = (source) ¶
