Examples of net.tomp2p.p2p.Peer

net.tomp2p.p2p.Peer
This is the main class to start DHT operations. This class makes use of the build pattern and for each DHT operation, a builder class is returned. The main operations can be initiated with {@link #put(Number160)}, {@link #get(Number160)}, {@link #add(Number160)}, {@link #addTracker(Number160)}, {@link #getTracker(Number160)}, {@link #remove(Number160)}, {@link #submit(Number160,Worker)}, {@link #send(Number160)}, {@link #sendDirect()}, {@link #broadcast(Number160)}. Each of those operations return a builder that offers more options. One of the main difference to a "regular" DHT is that TomP2P can store a map (key-values) instead of just values. To distinguish those, the keys are termed location key (for finding the right peer in the network), and content key (to store more than one value on a peer). For the put builder e.g. the following options can be set:
- {@link PutBuilder#setData(Number160,net.tomp2p.storage.Data)} - puts a content key with a value
- {@link PutBuilder#dataMap(Map) - puts multiple content key / values at once
- {@link PutBuilder#setPutIfAbsent() - only puts data if its not already on the peers
- ...
Furthermore, TomP2P also provides to store keys in different domains to avoid key collisions }( {@link PutBuilder#setDomainKey(Number160)).} @author Thomas Bocek
