Type Parameters:

V - the type of the result of the computation

All Superinterfaces:

Future<V>

public interface ListenableFuture<V>
extends Future<V>

Method Details

addDoneListener

void addDoneListener(Runnable listener)

Adds a listener to run on successful or unsuccessful completion of the asynchronous computation. The listener will run immediately if the computation is already complete when this method is called.

Adding this listener on the UI thread will cause it to be invoked on the UI thread, otherwise it is not guaranteed on which thread the listener is invoked.

Parameters:

listener - a Runnable to run when the computation is done

Throws:

IllegalArgumentException - if listener is null

Since:

100.0.0

removeDoneListener

boolean removeDoneListener(Runnable listener)

Removes a done listener so that it will not be called when the computation completes.

Parameters:

listener - the listener to be removed

Returns:

true if the listener was removed, otherwise false

Since:

100.0.0

toCompletableFuture

CompletableFuture<V> toCompletableFuture()

Returns a CompletableFuture wrapping for this object.

Returns:

the completable future

Since:
