Interface DoubleBinaryOperator

All Superinterfaces:

BiFunction<Double,Double,Double>, BiFunction<Double,Double,Double>, BinaryOperator<Double>, BinaryOperator<Double>, DoubleBinaryOperator

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 DoubleBinaryOperator
extends BinaryOperator<Double>, DoubleBinaryOperator

Represents an operation upon two double-valued operands and producing a double-valued result. This is the primitive type specialization of BinaryOperator for double.

This is a functional interface whose functional method is applyAsDouble(double, double).

Since:

1.8

Method Details

applyAsDouble

double applyAsDouble(double left, double right)

Applies this operator to the given operands.

Specified by:

applyAsDouble in interface DoubleBinaryOperator

Parameters:

left - the first operand

right - the second operand

Returns:

the operator result

apply

default Double apply(Double t, Double u)

Applies this function to the given arguments.

Specified by:

apply in interface BiFunction<Double,Double,Double>

Specified by:

apply in interface BiFunction<Double,Double,Double>

Parameters:

t - the first function argument

u - the second function argument

Returns:

the function result

applyPartial

default DoubleSupplier applyPartial(double t, double u)

Performs a partial application, resulting in a function that calls this with its argument and the argument given here.

Parameters:

t - the first function argument

u - the second function argument

Returns:

the function result

applyPartialL

default DoubleUnaryOperator applyPartialL(double t)

Performs a partial application, resulting in a function that calls this with its argument and the argument given here.

Parameters:

t - the function argument

Returns:

the function result

applyPartialR

default DoubleUnaryOperator applyPartialR(double u)

Performs a partial application, resulting in a function that calls this with its argument and the argument given here.

Parameters:

u - the function argument

Returns:

the function result

consume

default ObjDoubleConsumer<Double> consume(DoubleConsumer consumer)

Consume a function.

Parameters:

consumer - The consumer to use in consuming.

Returns:

A Consumer which passes it's argument to this function and then passes the result into the given consumer.

map

default DoubleBinaryOperator map(DoubleUnaryOperator functor)

Lift a function.

Parameters:

functor - The function to use in lifting.

Returns:

A function that passes the result of fn through a functor to produce a lifted function.
