Interface Throwing.Function2<V1,V2,R>

Type Parameters:

V1 - Input type.

V2 - Input type.

R - Output type.

All Superinterfaces:

BiFunction<V1,V2,R>

Enclosing class:

Throwing

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 static interface Throwing.Function2<V1,V2,R>
extends BiFunction<V1,V2,R>

Throwable version of BiFunction. The apply(Object, Object) method throws checked exceptions using Throwing.sneakyThrow(Throwable) method.
