Interface BinaryOperator<T>

Type Parameters:

T - the operand and result type

All Superinterfaces:

BiFunction<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 BinaryOperator<T>
extends BiFunction<T,T,T>

An operation on two values of one type that answers that type.
