Examples of net.tomp2p.futures.FutureRouting

net.tomp2p.futures.FutureRouting
The routing future keeps track of the routing process. This means that the routing future is returned immediately and the routing process starts in the background. There are two ways to wait for the routing process: (1) to use await*, which blocks the current thread and waits for the routing process to complete, or (2) to use addListener*, which will be called when the routing process completes. The listener may or may not run in the same thread. The routing will always succeed if we do DHT operations or bootstrap to ourself. It will fail if we bootstrap to another peer, but could not contact any peer than ourself. @see #neighbors(SortedSet,SortedSet,SortedSet,boolean,boolean) @author Thomas Bocek
