Interface DoubleToIntIOFunction

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 DoubleToIntIOFunction

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

Method Summary

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