Examples of org.jgroups.View

org.jgroups.View
A view is a local representation of the current membership of a group. Only one view is installed in a channel at a time. Views contain the address of its creator, an ID and a list of member addresses. These adresses are ordered, and the first address is always the coordinator of the view. This way, each member of the group knows who the new coordinator will be if the current one crashes or leaves the group. The views are sent between members using the VIEW_CHANGE event @author Bela Ban @version $Id: View.java,v 1.20 2008/02/20 15:51:57 belaban Exp $
