Insomnia is a simple cross-platform toolkit that allows the programmer to prevent the operating system to enter in sleep mode.

Usage example:

import ch.fever.insomnia.Insomnia;
import ch.fever.insomnia.InsomniaMode;

import java.util.Optional;

public class MyMediaApp {
    public void main(String args[]) {
        Optional<Insomnia> insomnia = Insomnia.getOptInstance();

        insomnia.ifPresent(i -> i.apply(InsomniaMode.SYSTEM_AND_DISPLAY_UP));

        // display a nice animation

        insomnia.ifPresent(i -> i.apply(InsomniaMode.DISABLED));
