Examples of org.jgroups.stack.Protocol.up()

org.jgroups.stack.Protocol.up()
An event was received from the layer below. Usually the current layer will want to examine the event type and - depending on its type - perform some computation (e.g. removing headers from a MSG event type, or updating the internal membership list when receiving a VIEW_CHANGE event). Finally the event is either a) discarded, or b) an event is sent down the stack using passDown() or c) the event (or another event) is sent up the stack using passUp().

            for(Map.Entry<String,Protocol> entry: up_prots.entrySet()) {
                String tmp=entry.getKey();
                if(tmp.startsWith(Global.DUMMY))
                    continue;
                Protocol prot=entry.getValue();
                prot.up(new Event(Event.SET_LOCAL_ADDRESS, local_addr));
            }
        }
