MethodMapping

class sklearn.utils.metadata_routing.MethodMapping

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 yields MethodPair(caller, callee) instances.

Added in version 1.3.

Add a method mapping.

Parameters:

callerstr

Parent estimator’s method name in which the callee is called.
