def inference_tip(infer_function, raise_on_overwrite=False): (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
