Interface DistributedBinaryOperator<T>

Type Parameters:

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

All Superinterfaces:

java.util.function.BiFunction<T,T,T>, java.util.function.BinaryOperator<T>, Serializable

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 DistributedBinaryOperator<T>
extends java.util.function.BinaryOperator<T>, Serializable

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

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

DistributedBiFunction, DistributedUnaryOperator
