Interface ThrowingUnaryOperation<T>

  • Type Parameters:
    T - the type of the input to the function
    All Superinterfaces:
    ThrowingFunction<T,​T>
    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 ThrowingUnaryOperation<T>
extends ThrowingFunction<T,​T>
    Represents an operation on a single operand that produces a result of the same type as its operand. This is a specialization of Function for the case where the operand and result are of the same type.

    When you find yourself in a situation where you need to use a function ( that throws an exception), this class is what you need to achieve your goal without Java complaining.

    The class Represents a function that accepts one argument and produces a result. whose functional method is ThrowingFunction.apply(Object).
