mypy.server.astmerge.NodeReplaceVisitor

class documentation

class NodeReplaceVisitor(TraverserVisitor): (source)

Transform some nodes to new identities in an AST.

Only nodes that live in the symbol table may be replaced, which simplifies the implementation some. Also replace all references to the old identities.

def __init__(self, replacements): (source)

overrides mypy.traverser.TraverserVisitor.__init__

Undocumented

Parameters
replacements:`Dict[SymbolNode, SymbolNode]`	Undocumented

def fixup(self, node): (source)

Undocumented

Parameters
node:`SN`	Undocumented
Returns
`SN`	Undocumented

def fixup_and_reset_typeinfo(self, node): (source)

Fix-up type info and reset subtype caches.

This needs to be called at least once per each merged TypeInfo, as otherwise we may leak stale caches.

Parameters

Returns
`TypeInfo`	Undocumented

def fixup_type(self, typ): (source)

Undocumented

Parameters
typ:`Optional[Type]`	Undocumented

def process_base_func(self, node): (source)

Undocumented

Parameters
