Package software.amazon.awssdk.iot

Class V2ClientFuture<T>

java.lang.Object

java.util.concurrent.CompletableFuture<T>

software.amazon.awssdk.iot.V2ClientFuture<T>

Type Parameters:

T -

All Implemented Interfaces:

CompletionStage<T>, Future<T>

public class V2ClientFuture<T>
extends CompletableFuture<T>

CompletableFuture variant used internally to chain from a generic callback to a type-specific callback. We need to keep the generic future alive from a garbage collection perspective so that its .whenComplete(...) control flow path will complete this future. I cannot tell from documentation if this is truly necessary. Does a completion stage have a reference to its predecessor?
