Instances of this class represent the core JXTA peergroup service. The peergroup service forms the basis of a number of JXTA operations that every peer must undertake.
JXTA peers typically
join the NetPeerGroup by calling the
newNetPeerGroup( ) method of the
which returns a peergroup object. Alternately, they may use the
newPeerGroup( ) method of the PeerGroupFactory to
join the NetPeerGroup, which also returns a peergroup object. In
either case, the returned object is used to locate the core JXTA
services: discovery, membership, and so on. In general, peers are

other peergroups and use the services of the other peergroups to

New peergroups are created by the
newGroup( ) method of this interface. You must
have a new peergroup advertisement in order to make a new peergroup.
This is usually accomplished by discovering the peergroup
advertisement that you’re interested in: you

getDiscoveryService( ) method) and use it to find
