Examples of org.jgroups.stack.StaticInterval

org.jgroups.stack.StaticInterval
Manages retransmission timeouts. Always returns the next timeout, until the last timeout in the array is reached. Returns the last timeout from then on. Note that this class is immutable, so it shouldn't be shared between instances, as {@link #next()} will modify the state. @author John Giorgiadis @author Bela Ban @version $Id: StaticInterval.java,v 1.3 2007/08/10 12:47:38 belaban Exp $
