Function clear_inference_tip_cache Clear the inference tips cache.
Function inference_tip Given an instance specific inference function, return a function to be given to AstroidManager().register_transform to set this inference function.
Type Alias InferFn Undocumented

Clear the inference tips cache.

def inference_tip(infer_function: InferFn, raise_on_overwrite: bool = False) -> InferFn: (source)

Given an instance specific inference function, return a function to be given to AstroidManager().register_transform to set this inference function.

Typical usage

AstroidManager().register_transform(Call, inference_tip(infer_named_tuple),
                           predicate)

Note

Using an inference tip will override any previously set inference tip for the given node. Use a predicate in the transform to prevent excess overwrites.

Parameters
infer_function:InferFnUndocumented
raise_on_overwrite:boolUndocumented
bool raise_on_overwriteRaise an InferenceOverwriteError if the inference tip will overwrite another. Used for debugging
Returns

InferFn = (source)
