Interface ExDoubleFunction<R, E extends Exception>

Type Parameters:

R - the type of the result of the function

E - the type of exception thrown

All Superinterfaces:

Wrappable<DoubleFunction<R>>

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 ExDoubleFunction<R, E extends Exception>
extends Wrappable<DoubleFunction<R>>

Equivalent of a DoubleFunction that can throw exceptions.

Method Summary

Modifier and Type	Method	Description
R	apply(double value)	Applies this function to the given argument.
default @NonNull DoubleFunction<R>	wrap()	Wraps this functional interface, allowing it to be used in contexts where exceptions are not allowed to be thrown directly.

Method Details

apply

R apply(double value)
 throws E

Applies this function to the given argument.

Parameters:

value - the function argument

Returns:

the function result

Throws:

E - potentially

wrap

default @NonNull DoubleFunction<R> wrap()

Description copied from interface: Wrappable

Wraps this functional interface, allowing it to be used in contexts where exceptions are not allowed to be thrown directly.

If a checked exception is thrown, an ExException, which is a runtime exception, will be thrown instead. This will have the original exception as its cause.

Specified by:

wrap in interface Wrappable<R>

Returns:

a wrapped instance of type W
