Class FutureLaterJoin<K extends BaseFuture>

java.lang.Object
  net.tomp2p.futures.BaseFutureImpl<FutureLaterJoin<K>>

Type Parameters:

K -

All Implemented Interfaces:

BaseFuture, Cancellable

public class FutureLaterJoin<K extends BaseFuture>
extends BaseFutureImpl<FutureLaterJoin<K>>
implements BaseFuture

FutureLaterJoin is similar to FutureLateJoin. The main difference is that with this class you don't need to specify all the futures in advance and you don't need to specify how many futures you expect. Once you are done, just call done().

Constructor Detail

FutureLaterJoin

public FutureLaterJoin()

Create this future.

Method Detail

add

public boolean add(K future)

Add a future when ready. This is why its called FutureLateJoin, since you can add futures later on.

Parameters:

future - The future to be added.

Returns:

True if the future was added to the futurelist, false if the latejoin future is already finished and the future was not added.

done

public void done()

If no more futures are added, done() must be called to evaluate the results. If the futures already finished by the time done() is called, the listeners are called from this thread. Otherwise the notify may be called from a different thread.

done

public void done(int minSuccess)

If no more futures are added, done() must be called to evaluate the results. If the futures already finished by the time done() is called, the listeners are called from this thread. Otherwise the notify may be called from a different thread.

Parameters:

minSuccess - The number of minimum futures that needs to be successful to consider this future as a success.

getFuturesDone

public List<K> getFuturesDone()

Returns the finished futures.

Returns:

All the futures that are done.

getLastSuceessFuture

public K getLastSuceessFuture()

Returns:

the last successful finished future.
