no.motif.f.alias

Interface Reducer<I1,I2,O>

All Superinterfaces:

Fn2<I1,I2,O>, Serializable

public interface Reducer<I1,I2,O>
extends Fn2<I1,I2,O>

A Reducer can be implemented in place of an Fn2 to communicate that the functions reduces two values to one. This type does not provide anything over Fn2 but, where appropriate, being a more specific nominative type, solely for communication purposes.

Good practice

One should never accept Reducers as argument types, but always implement method signatures to accept Fn2.
