Interface IntToDoubleIOFunction

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 IntToDoubleIOFunction

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

Method Summary

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