Examples of org.apache.catalina.tribes.Member

org.apache.catalina.tribes.Member
The Member interface, defines a member in the Cluster. A member is a Tomcat process that participates in session replication.
Each member can carry a set of properties, defined by the actual implementation.
For TCP replication has been targeted for the first release, the hostname and listen port of the member is defined as hardcoded stuff.
The Member interface together with MembershipListener, MembershipService are interfaces used to switch out the service used to establish membership in between the cluster nodes. @author Filip Hanik @version $Revision: 303950 $, $Date: 2005-06-09 15:38:30 -0500 (Thu, 09 Jun 2005) $
