# `sklearn.utils.metadata_routing`.MethodMapping

sklearn.utils.metadata_routing.MethodMapping()

  Stores the mapping between callee and caller methods for a router.

  This class is primarily used in a `get_metadata_routing()` of a router object when defining the mapping between a sub-object (a sub-estimator or a scorer) to the router’s methods. It stores a collection of `Route` namedtuples.

  Iterating through an instance of this class will yield named `MethodPair(callee, caller)` tuples.

  New in version 1.3.
