Interface IOBinaryOperator<T>

Type Parameters:

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

All Superinterfaces:

IOBiFunction<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 IOBinaryOperator<T>
extends IOBiFunction<T,T,T>

Like BinaryOperator but throws IOException.

Since:

2.12.0

IOBiFunction, BinaryOperator

Method Summary

Modifier and Type	Method and Description
default java.util.function.BinaryOperator<T>	asBinaryOperator() Creates a BinaryOperator for this instance that throws UncheckedIOException instead of IOException.
static <T> IOBinaryOperator<T>	maxBy(IOComparator<? super T> comparator) Creates a IOBinaryOperator which returns the greater of two elements according to the specified Comparator.
static <T> IOBinaryOperator<T>	minBy(IOComparator<? super T> comparator) Creates a IOBinaryOperator which returns the lesser of two elements according to the specified Comparator.

Method Detail

maxBy

static <T> IOBinaryOperator<T> maxBy(IOComparator<? super T> comparator)

Creates a IOBinaryOperator which returns the greater of two elements according to the specified Comparator.

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

minBy

static <T> IOBinaryOperator<T> minBy(IOComparator<? super T> comparator)

Creates a IOBinaryOperator which returns the lesser of two elements according to the specified Comparator.

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 lesser of its operands, according to the supplied Comparator

Throws:

java.lang.NullPointerException - if the argument is null

asBinaryOperator

default java.util.function.BinaryOperator<T> asBinaryOperator()

Creates a BinaryOperator for this instance that throws UncheckedIOException instead of IOException.

Returns:

an unchecked BiFunction.
