Class FixedMembershipToken

java.lang.Object
  org.jgroups.auth.AuthToken
      org.jgroups.auth.FixedMembershipToken

All Implemented Interfaces:

extends AuthToken

The FixedMemberShipToken object predefines a list of IP addresses and Ports that can join the group.

Configuration parameters for this example are shown below:

• fixed_members_value (required) = List of IP addresses & ports (optionally) - ports must be seperated by a '/' e.g. 127.0.0.1/1010*127.0.0.1/4567
