DoubleUnaryOperatorWithThrowable (throwable-interfaces 1.13 API)

Type Parameters:

E - The extension

All Superinterfaces:

DoubleUnaryOperator

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 DoubleUnaryOperatorWithThrowable<E extends Throwable>
extends DoubleUnaryOperator
```
Generated from DoubleUnaryOperator Extends java.util.function.DoubleUnaryOperator to allow for a checked exception.
