sklearn.utils.metaestimators.if_delegate_has_method

sklearn.utils.metaestimators.if_delegate_has_method(delegate)

Create a decorator for methods that are delegated to a sub-estimator

This enables ducktyping by hasattr returning True according to the sub-estimator.

Deprecated since version 1.3: if_delegate_has_method is deprecated in version 1.1 and will be removed in version 1.3. Use available_if instead.

Parameters:

delegatestr, list of str or tuple of str

Name of the sub-estimator that can be accessed as an attribute of the base object. If a list or a tuple of names are provided, the first sub-estimator that is an attribute of the base object will be used.
