DoubleIOFunction (io-functions 2.0 API)

Type Parameters:

R - The type of the result of the function.

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 DoubleIOFunction<R>
```
Represents a function that accepts a double-valued argument and produces a result. This is the IOException throwing equivalent of DoubleFunction.

Method Summary

All Methods Static Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`R`	`apply(double value)` Applies this function to the given argument.
`static <R> DoubleIOFunction<R>`	`checked(DoubleFunction<? extends R> function)` Returns a function that applies the `function` function to its input, and unwraps any `UncheckedIOException` that is thrown by throwing its `cause`.
`static <R> DoubleFunction<R>`	`unchecked(DoubleIOFunction<? extends R> function)` Returns a function that applies the `function` function to its input, and wraps any `IOException` that is thrown in an `UncheckedIOException`.

  - apply
```
R apply(double value)
 throws IOException
```
    Applies this function to the given argument.
    
    Parameters:
    
    value - The function argument.
    
    Returns:
    
    The function result.
    
    Throws:
    
    IOException - If an I/O error occurs.
  - unchecked
```
static <R> DoubleFunction<R> unchecked(DoubleIOFunction<? extends R> function)
```
    Returns a function that applies the function function to its input, and wraps any IOException that is thrown in an UncheckedIOException.
    
    Type Parameters:
    
    R - The type of the result of the function.
    
    Parameters:
    
    function - The function to apply when the returned function is applied.
    
    Returns:
    
    A function that applies the function function to its input, and wraps any IOException that is thrown in an UncheckedIOException.
    
    Throws:
    
    NullPointerException - If function is null.
  - checked
```
static <R> DoubleIOFunction<R> checked(DoubleFunction<? extends R> function)
```
    Returns a function that applies the function function to its input, and unwraps any UncheckedIOException that is thrown by throwing its cause.
    
    Type Parameters:
    
    R - The type of the result of the function.
    
    Parameters:
    
    function - The function to apply when the returned function is applied.
    
    Returns:
    
    A function that applies the function function to its input, and unwraps any UncheckedIOException that is thrown.
    
    Throws:
    
    NullPointerException - If function is null.
