Interface ThrowableDoubleUnaryOperator

All Superinterfaces:

java.util.function.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 ThrowableDoubleUnaryOperator
extends java.util.function.DoubleUnaryOperator

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

Permits checked exceptions unlike DoubleUnaryOperator

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