Examples of net.tomp2p.futures.FutureAsyncTask

net.tomp2p.futures.FutureAsyncTask
A future to keep track of a future task. The task is submitted using an RPC, then a scheduled task keeps polling the peer if the peer is still alive. If the peer dies, this future is notified. If the remote peer finishes the task, the remote peer sends an RPC to the initiating peer that the task is finished. @author Thomas Bocek
