Interface AsyncCloseable
public interface AsyncCloseable
Interface for close operations that are asynchronous.
Asynchronously closing a class
In the snippet below, we have a long-lived NetworkResource
class. There are some operations such
as closing I/O. Instead of returning a sync close()
, we use closeAsync()
so users'
programs don't block waiting for this operation to complete.
NetworkResource resource = new NetworkResource(); resource.longRunningDownload("https://longdownload.com") .subscribe( byteBuffer -> System.out.println("Buffer received: " + byteBuffer), error -> System.err.printf("Error occurred while downloading: %s%n", error), () -> System.out.println("Completed download operation.")); System.out.println("Press enter to stop downloading."); System.in.read(); // We block here because it is the end of the main Program function. A real-life program may chain this // with some other close operations like save download/program state, etc. resource.closeAsync().block();
