AsyncTask

Java 1.8 library that facilitates asynchronous programming.

<artifactId>AsyncTask</artifactId>
<version>1.0</version>

Examples

VoidTask.run(() -> {
    System.out.println("Hello!");
});

This creates a new VoidTask - a task that returns nothing - and runs it without waiting for the result.

There are two ways of waiting for a Task to finish.

1. Using the await method which blocks the current thread until the task is completed

Task task = VoidTask.run(() -> {
    System.out.println("Hello!");
});
task.await();

2. Using the then and error callbacks

VoidTask.run(() -> {
    System.out.println("Hello!");
}).then(() -> {
    System.out.println("Hello task completed!");
}).error(exception -> {
    System.out.println("Hello task failed :(");
    exception.printStackTrace();
});

---

ValueTask.run(() -> {
    return "Todd";
});

This creates a new ValueTask that returns a String (Todd) and runs it without waiting for the result.

You can wait for the result of a ValueTask the same way that you would wait for the result of a VoidTask, but ValueTask returns the result in the callback

ValueTask.run(() -> {
    return "Todd";
}).then((t, result) -> {
    System.out.println("My cat is named: " + result);
});

Why does this exist? Why don't use an established library?

We didn't want a bloated library just to use 5% of it.
