org.cactoos.func

Class AsyncFunc<X,Y>

java.lang.Object

org.cactoos.func.AsyncFunc<X,Y>

Type Parameters:

X - Type of input

Y - Type of output

All Implemented Interfaces:

Func<X,Future<Y>>, Proc<X>

public final class AsyncFunc<X,Y>
extends Object
implements Func<X,Future<Y>>, Proc<X>

Func that runs in the background.

If you want your piece of code to be executed in the background, use AsyncFunc as following:

 int length = new AsyncFunc(
   input -> input.length()
 ).apply("Hello, world!").get();

There is no thread-safety guarantee.

Since:

0.10
