Interface DoubleToLongIOFunction

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 DoubleToLongIOFunction

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

Method Summary

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