This class is used by Jxta applications to create new groups <p/> JXTA comes with two subclasses of peer groups: <ul type-disc> <li> <strong>Platform</strong>: this is used to represent the <em>World</em> group. Every peer, when booting, becomes part of this group. This group provides the minimum core services needed to find and instanciate other groups on a peer. <strong>Platform</strong> has the privilege of assigning a new ID to the peer, if it does not already have one. The <em>World</em> group's ID is invariant.</li> <li> <strong>StdPeergroup</strong>: this is currently used to implement all other kinds of peer groups. The first such group that it is instanciated after booting is known as <em>The Net Peer Group</em>. When <strong>Platform</strong> starts it may optionaly search for <em>The Net Peer Group</em> on the local network and, if found, instanciate it. Otherwise a default configuration of <em>The Net Peer Group</em> is instanciated. A non-default configuration of <em>The Net Peer Group</em> may be set-up by the administrator in charge of the network domain inside which the peer is booting. <em>The Net Peer Group</em> is discovered via the DiscoveryService protocol. Many such groups may be configured by an administrator.<br> <strong>StdPeergroup</strong> may also be used to implement User-defined peer groups: Users can create new peer groups which use their own set of customized services.</li></ul> <p/>The Platform group is created via the <b>newPlatform</b> method. The Net Peer Group and user Peer Groups are created via the <b>newPeerGroup</b> method.<P><P><DL><DT><B>See Also:</B><DD><A HREF="../../../net/jxta/peergroup/PeerGroup.html" title="interface in
