TomP2P implements besides the following distributed hash table (DHT)
operations:
value=get(locationKey)
put(locationKey,value)
remove(locationKey)
also the following operations:
value=get(locationKey,contentKey)
put(locationKey,contentKey,value)
remove(locationKey,contentKey)
The advantage of TomP2P is that multiple values can be stored in one
location.
The reason NOT_REACHABLE means that the peer is offline and cannot be
contacted, while REMOVED_FROM_MAP means that this peer has been removed
from the neigbhor list, but may still be reachable.
