Interface BinaryOperatorEx<T,E extends java.lang.Throwable>

Type Parameters:

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

E - the type of exception could be thrown while performing operation

All Superinterfaces:

BiFunctionEx<T,T,T,E>

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 BinaryOperatorEx<T,E extends java.lang.Throwable>
extends BiFunctionEx<T,T,T,E>

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 BiFunctionEx for the case where the operands and the result are all of the same type.

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

Type Parameters:

T - the type of the input arguments of the comparator

Parameters:

comparator - a Comparator for comparing the two values

Returns:

a BinaryOperator which returns the greater of its operands, according to the supplied Comparator

Throws:

java.lang.NullPointerException - if the argument is null
