Class Data

java.lang.Object

net.tomp2p.storage.Data

All Implemented Interfaces:

Serializable

public class Data
extends Object
implements Serializable

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.
