class basics.TypingCollector¶

Bases: libcst.CSTVisitor

The low-level base visitor class for traversing a CST. This should be used in conjunction with the visit() method on a CSTNode to visit each element in a tree starting with that node. Unlike CSTTransformer, instances of this class cannot modify the tree.

When visiting nodes using a CSTVisitor, the return value of visit() will equal the passed in tree.

visit_ClassDef(self, node: libcst.ClassDef) → Optional[bool]¶

Parameters: node (libcst.ClassDef) –
Return type: Optional[bool]

leave_ClassDef(self, node: libcst.ClassDef) → None¶

Parameters: node (libcst.ClassDef) –
Return type: None

visit_FunctionDef(self, node: libcst.FunctionDef) → Optional[bool]¶

Parameters: node (libcst.FunctionDef) –
Return type: Optional[bool]

leave_FunctionDef(self, node: libcst.FunctionDef) → None¶

Parameters: node (libcst.FunctionDef) –
Return type: None

class basics.TypingTransformer(annotations)¶

Bases: libcst.CSTTransformer

The low-level base visitor class for traversing a CST and creating an updated copy of the original CST. This should be used in conjunction with the visit() method on a CSTNode to visit each element in a tree starting with that node, and possibly returning a new node in its place.

When visiting nodes using a CSTTransformer, the return value of visit() will be a new tree with any changes made in on_leave() calls reflected in its children.

visit_ClassDef(self, node: libcst.ClassDef) → Optional[bool]¶

Parameters: node (libcst.ClassDef) –
Return type: Optional[bool]

leave_ClassDef(self, original_node: libcst.ClassDef, updated_node: libcst.ClassDef) → libcst.CSTNode¶

Parameters

original_node (libcst.ClassDef) –
updated_node (libcst.ClassDef) –

Return type

libcst.CSTNode
