A few useful function/method decorators.

Class cachedproperty Provides a cached property equivalent to the stacking of @cached and @property, but more efficient.
Function cached Simple decorator to cache result of method calls without args.
Function deprecate_default_argument_values Decorator which emitts a DeprecationWarning if any arguments specified are None or not passed at all.

def cached(func, instance, args, kwargs): (source)

Simple decorator to cache result of method calls without args.

def deprecate_default_argument_values(astroid_version: str = '3.0', **arguments: str) -> Callable[[Callable[P, R]], Callable[P, R]]: (source)

Decorator which emitts a DeprecationWarning if any arguments specified are None or not passed at all.

Arguments should be a key-value mapping, with the key being the argument to check and the value being a type annotation as string for the value of the argument.

return the given infer function wrapped to handle the path

Used to stop inference if the node has already been looked at for a given InferenceContext to prevent infinite recursion
