Interface Remote.BinaryOperator<T>

Type Parameters:

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

All Superinterfaces:

BiFunction<T,T,T>, BinaryOperator<T>, Remote.BiFunction<T,T,T>, Serializable

Enclosing class:

Remote

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 Remote.BinaryOperator<T>
extends Remote.BiFunction<T,T,T>, 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 BiFunction 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).
