java.lang.Object

jadex.future.Future<Collection<E>>

jadex.future.IntermediateFuture<E>

jadex.future.TerminableIntermediateFuture<E>

All Implemented Interfaces:

IBackwardCommandFuture, IForwardCommandFuture, IFuture<Collection<E>>, IIntermediateFuture<E>, ITerminableFuture<Collection<E>>, ITerminableIntermediateFuture<E>, Supplier<Collection<E>>

Direct Known Subclasses:

PullIntermediateFuture, SubscriptionIntermediateFuture

public class TerminableIntermediateFuture<E>
extends IntermediateFuture<E>
implements ITerminableIntermediateFuture<E>

Intermediate 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.

Constructor Details

TerminableIntermediateFuture

public TerminableIntermediateFuture()

Create a new future.

TerminableIntermediateFuture

public TerminableIntermediateFuture(Exception exception)

Create a future that is already done (failed).

Parameters:

exception - The exception.

TerminableIntermediateFuture

public TerminableIntermediateFuture(ITerminationCommand terminate)

Create a new future.

Parameters:

terminate - The runnable to be executed in case of termination.

Method Details

terminate

public void terminate()

Terminate the future. The exception will be set to FutureTerminatedException.

Specified by:

terminate in interface ITerminableFuture<E>

terminate

public void terminate(Exception reason)

Terminate the future and supply a custom reason.

Specified by:

terminate in interface ITerminableFuture<E>

getTerminationCommand

public ITerminationCommand getTerminationCommand()

Get the terminate.

Returns:

The terminate.

setTerminationCommand

public void setTerminationCommand(ITerminationCommand terminate)

Set the terminate.

Parameters:

terminate - The terminate to set.

sendBackwardCommand

public void sendBackwardCommand(Object info)

Send a backward command in direction of the source.

Specified by:

sendBackwardCommand in interface IBackwardCommandFuture

Parameters:

info - The command info.

addBackwardCommand

public void addBackwardCommand(jadex.common.IFilter<Object> filter,
 jadex.common.ICommand<Object> command)

Add a backward command with a filter. Whenever the future receives an info it will check all registered filters.

removeBackwardCommand

public void removeBackwardCommand(jadex.common.ICommand<Object> command)

Add a command with a filter. Whenever the future receives an info it will check all registered filters.
