or c) the event (or another event) is sent up the stack using up_prot.up()
.public void up(MessageBatch batch)
Protocol
MessageBatch
. The sender of the batch is always the same, and so is the
destination (null == multicast messages). Messages in a batch can be OOB messages, regular messages, or mixed
messages, although the transport itself will create initial MessageBatches that contain only either OOB or
regular messages.
The default processing below sends messages up the stack individually, based on a matching criteria
(calling Protocol.accept(org.jgroups.Message)
), and - if true - calls Protocol.up(org.jgroups.Event)
for that message and removes the message. If the batch is not empty, it is passed up, or else it is dropped.
Subclasses should check if there are any messages destined for them (e.g. using
MessageBatch.getMatchingMessages(short,boolean)
), then possibly remove and process them and finally pass
the batch up to the next protocol. Protocols can also modify messages in place, e.g. ENCRYPT could decrypt all
encrypted messages in the batch, not remove them, and pass the batch up when done.public Object down(Event evt)
