Interface LongToDoubleIOFunction

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 LongToDoubleIOFunction

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

Method Summary

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