org.jgroups.stack.ProtocolStack
A ProtocolStack manages a number of protocols layered above each other. It creates all protocol classes, initializes them and, when ready, starts all of them, beginning with the bottom most protocol. It also dispatches messages received from the stack to registered objects (e.g. channel, GMP) and sends messages sent by those objects down the stack.
The ProtocolStack makes use of the Configurator to setup and initialize stacks, and to destroy them again when not needed anymore @author Bela Ban @version $Id: ProtocolStack.java,v 1.59.2.4 2008/02/15 01:05:11 vlada Exp $
