Interface ToIntIOFunction<T>

Type Parameters:

T - The type of the input to 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 ToIntIOFunction<T>

Represents a function that produces an int-valued result. This is the IOException throwing equivalent of ToIntFunction.

Method Summary

Modifier and Type	Method and Description
int	applyAsInt(T value) Applies this function to the given argument.
static <T> ToIntIOFunction<T>	checked(ToIntFunction<? super T> function) Returns a function that applies the function function to its input, and unwraps any UncheckedIOException that is thrown by throwing its cause.
static <T> ToIntFunction<T>	unchecked(ToIntIOFunction<? super T> function) Returns a function that applies the function function to its input, and wraps any IOException that is thrown in an UncheckedIOException.

Method Detail

applyAsInt

int applyAsInt(T 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 <T> ToIntFunction<T> unchecked(ToIntIOFunction<? super T> function)

Returns a function that applies the function function to its input, and wraps any IOException that is thrown in an UncheckedIOException.

Type Parameters:

T - The type of the first argument to 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 <T> ToIntIOFunction<T> checked(ToIntFunction<? super T> 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:

T - The type of the first argument to 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.
