net.ashwork.functionality.arity.operator

Interface Operator3<T>

Type Parameters:

T - The type of the operands and result of the operator

All Superinterfaces:

Function3<T,T,T,T>

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 Operator3<T>
extends Function3<T,T,T,T>

Represents an operation upon three operands of the same type, producing a result of the same type as the operands. This is a specialization of Function3 for the case where the operands and the result are all of the same type.

This is a functional interface whose functional method is Function3.apply(Object, Object, Object).

Since:

2.0.0
