org.apache.catalina.tribes.membership.Membership
A membership implementation using simple multicast. This is the representation of a multicast membership. This class is responsible for maintaining a list of active cluster nodes in the cluster. If a node fails to send out a heartbeat, the node will be dismissed. @author Filip Hanik @author Peter Rossbach @version $Id: Membership.java 939515 2010-04-29 23:59:49Z kkolinko $
