MethodMapping (original) (raw)

class sklearn.utils.metadata_routing.MethodMapping[source]#

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

This class is primarily used in a get_metadata_routing() of a router object when defining the mapping between the router’s methods and a sub-object (a sub-estimator or a scorer).

Iterating through an instance of this class yieldsMethodPair(caller, callee) instances.

Added in version 1.3.
