Interface IntToLongIOFunction

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 IntToLongIOFunction

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

Method Summary

Modifier and Type	Method and Description
long	applyAsLong(int value) Applies this function to the given argument.
static IntToLongIOFunction	checked(IntToLongFunction function) Returns a function that applies the function function to its input, and unwraps any UncheckedIOException that is thrown by throwing its cause.
static IntToLongFunction	unchecked(IntToLongIOFunction function) Returns a function that applies the function function to its input, and wraps any IOException that is thrown in an UncheckedIOException.
