Interface LongIOFunction<R>

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 LongIOFunction<R>

Represents a function that accepts a long-valued argument and produces a result. This is the IOException throwing equivalent of LongFunction.

Method Summary

Modifier and Type	Method and Description
R	apply(long value) Applies this function to the given argument.
static <R> LongIOFunction<R>	checked(LongFunction<? 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> LongFunction<R>	unchecked(LongIOFunction<? extends R> function) Returns a function that applies the function function to its input, and wraps any IOException that is thrown in an UncheckedIOException.

Method Detail

apply

R apply(long value)
 throws IOException

Applies this function to the given argument.

Parameters:

value - The function argument.

Returns:

The function result.

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:

checked

static <R> LongIOFunction<R> checked(LongFunction<? 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.
