Examples of net.tomp2p.storage.Data

net.tomp2p.storage.Data
This class holds the data for the transport. The data is already serialized and a hash may be created. It is reasonable to create the hash on the remote peer, but not on the local peer. The remote peer uses the hash to tell the other peers, which version is stored and its used quite often. @author Thomas Bocek
