Interface ToIntBiFunction<T,​U>

Type Parameters:
T - the type of the first argument to the function
U - the type of the second argument to the function
All Superinterfaces:
BiFunction<T,​U,​Integer>, BiFunction<T,​U,​Integer>, ToIntBiFunction<T,​U>
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface
public interface ToIntBiFunction<T,​U>
extends BiFunction<T,​U,​Integer>, ToIntBiFunction<T,​U>
Represents a function that accepts two arguments and produces an int-valued result. This is the int-producing primitive specialization for BiFunction.

This is a functional interface whose functional method is applyAsInt(Object, Object).

Since:
