FutureDHT

public FutureDHT(DHTBuilder<?> builder)

Method Detail

builder

public DHTBuilder<?> builder()

Returns:

A reference to the builder that contains the data we were looking for

futureRequests

public FutureForkJoin<FutureResponse> futureRequests()

Returns back those futures that are still running. If 6 storage futures are started at the same time and 5 of them finish, and we specified that we are fine if 5 finishes, then futureDHT returns success. However, the future that may still be running is the one that stores the content to the closest peer. For testing this is not acceptable, thus after waiting for futureDHT, one needs to wait for the running futures as well.

Returns:

A future that finishes if all running futures are finished.

addRequests

public K addRequests(FutureResponse futureResponse)

Adds all requests that have been created for the DHT operations. Those were created after the routing process.

Parameters:

futureResponse - The futurRepsonse that has been created

addFutureDHTReleaseListener

public void addFutureDHTReleaseListener(ChannelCreator channelCreator)

Adds a listener to the response future and releases all aquired channels in channel creator.

Parameters:

channelCreator - The channel creator that will be shutdown and all connections will be closed

futureRouting

public FutureRouting futureRouting()

Returns the future object that was used for the routing. Before the FutureDHT is used, FutureRouting has to be completed successfully.

Returns:

The future object during the previous routing, or null if routing failed completely.

futureRouting

public void futureRouting(FutureRouting futureRouting)

Sets the future object that was used for the routing. Before the FutureDHT is used, FutureRouting has to be completed successfully.

Parameters:

futureRouting - The future object to set

futuresCompleted

public FutureDone<Void> futuresCompleted()
