done
public boolean done()
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).

getInstance
public static PERF_TP getInstance()
getNumMessages
public long getNumMessages()
getTotalTime
public long getTotalTime()
init
public void init()
throws Exception
Called after instance has been created (null constructor) and before protocol is started.
Properties are already set. Other protocols are not yet connected and events cannot yet be sent.

setExpectedMessages
public void setExpectedMessages(long m)
start
public void start()
throws Exception
This method is called on a
Channel.connect(String)
. Starts work.
Protocols are connected and queues are ready to receive events.
Will be called
from bottom to top. This call will replace
the
START and
START_OK events.

toString
public String toString()
up
public void up(Event evt)
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()
.
