java.lang.Object

org.jboss.as.protocol.mgmt.AsyncToCompletableFutureAdapter

public final class AsyncToCompletableFutureAdapter
extends Object

Utility that adapts an AsyncFuture to a CompletableFuture by using an AsyncFuture.Listener to complete or cancel the CompletableFuture and by ensuring calls to CompletableFuture.cancel(boolean) result in appropriate cancellation of the AsyncFuture.

Method Details

adapt

public static <T> CompletableFuture<T> adapt(org.jboss.threads.AsyncFuture<T> asyncFuture)

Adapt the given asyncFuture to complete or cancel a CompletableFuture.

Type Parameters:

T - the type provided by the futures

Parameters:

asyncFuture - the future that will provide the value. Cannot be null

adapt

public static <T,
U> CompletableFuture<U> adapt(org.jboss.threads.AsyncFuture<T> asyncFuture,
 Function<T,U> transformer,
 Consumer<Boolean> asyncCancelTask)

Adapt the given asyncFuture to complete or cancel a CompletableFuture. The given transformer function is applied before completing the CompletableFuture, allowing the CompletableFuture to provide a different type than the AsyncFuture.

Type Parameters:

T - the type provided by the asyncFuture

U - the type to be provided by the @{code CompletableFuture}

Parameters:

asyncFuture - the future that will provide the value. Cannot be null

transformer - a function to convert the type provided by asyncFuture to that provided by the CompletableFuture. Cannot be null

asyncCancelTask - optional function to perform async cancellation of the ActiveOperation, instead of a call to AsyncFutureTask.asyncCancel(boolean). May be null
