net.jxta.impl.membership.none
Class NoneMembershipService

java.lang.Object
  extended by net.jxta.impl.membership.none.NoneMembershipService
All Implemented Interfaces:
MembershipService, Module, Service
public class NoneMembershipService
extends Object
implements MembershipService

A Membership Service implementation which is intended to be used with peer groups which require no real authentication.

The none service allows you to claim any identity within the peergroup, but for peergroups which use this Membership Service method, it is likely that the identity is used only for informational purposes.

A default credential with the name "nobody" is automatically available without requiring authentication by this service.
