Interface DoubleUnaryOperatorEx<E extends java.lang.Throwable>

Type Parameters:

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

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 DoubleUnaryOperatorEx<E extends java.lang.Throwable>

Represents an operation on a single double-valued operand that produces a double-valued result. This is the primitive type specialization of UnaryOperatorEx for double.

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

Since:

1.8

Method Summary

Modifier and Type	Method and Description
default DoubleUnaryOperatorEx<E>	andThen(DoubleUnaryOperatorEx<E> after) Returns a composed operator that first applies this operator to its input, and then applies the after operator to the result.

Method Detail

identity

static <E extends java.lang.Throwable> DoubleUnaryOperatorEx<E> identity()

Returns a unary operator that always returns its input argument.

Returns:

a unary operator that always returns its input argument

applyAsDouble

double applyAsDouble(double operand)
              throws E extends java.lang.Throwable

Applies this operator to the given operand.

Parameters:

operand - the operand

Returns:

the operator result

Throws:

E extends java.lang.Throwable

compose

default DoubleUnaryOperatorEx<E> compose(DoubleUnaryOperatorEx<E> before)

Returns a composed operator that first applies the before operator to its input, and then applies this operator to the result. If evaluation of either operator throws an exception, it is relayed to the caller of the composed operator.

Parameters:

before - the operator to apply before this operator is applied

Returns:

a composed operator that first applies the before operator and then applies this operator

Throws:

java.lang.NullPointerException - if before is null

See Also:

andThen(DoubleUnaryOperatorEx)

andThen

default DoubleUnaryOperatorEx<E> andThen(DoubleUnaryOperatorEx<E> after)

Returns a composed operator that first applies this operator to its input, and then applies the after operator to the result. If evaluation of either operator throws an exception, it is relayed to the caller of the composed operator.

Parameters:

after - the operator to apply after this operator is applied

Returns:

a composed operator that first applies this operator and then applies the after operator

Throws:

java.lang.NullPointerException - if after is null
