public void up(Event evt)
- Description copied from class:
Protocol
- 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()
.
- Overrides:
up
in class Protocol
down
public void down(Event evt)
- Caller by the layer above this layer. Usually we just put this Message
into the send queue and let one or more worker threads handle it. A worker thread
then removes the Message from the send queue, performs a conversion and adds the
modified Message to the send queue of the layer below it, by calling Down).
- Overrides:
down
