Class TerminableFuture<E>

java.lang.Object

jadex.commons.future.Future<E>

jadex.commons.future.TerminableFuture<E>

All Implemented Interfaces:

IBackwardCommandFuture, IForwardCommandFuture, IFuture<E>, ITerminableFuture<E>

public class TerminableFuture<E>
extends Future<E>
implements ITerminableFuture<E>

Future that can be terminated from caller side. A termination request leads to setException() being called with a FutureTerminatedException. The future can be supplied with a command that gets executed if terminate is called.
