Description
Refreshes the information on the screen.
The PacketListener Role is one of the following:
ADVISOR
Examines the incoming packet. Might add processing hints to the message context,
but does not modify the packet out message.
DIRECTOR
Processes the packet. Might add actions or instructions to the packet-out message.
Can instruct the controller to block the packet, or to send the packet out.
OBSERVER
A passive observer who might examine the incoming packet and any packet-out
response.
Packets are given to packet listeners with role of ADVISOR first, DIRECTOR second,
and OBSERVER third. Every packet listener is guaranteed to see the packet-in
message. Depending on the action taken by higher altitude Directors, a lower altitude
Director might be too late to influence the packet processing.
The weight or priority this packet listener should have relative to other packet listeners
that have the same role. The controller gives packet listeners with higher numbers
priority over packet listeners with lower numbers.
The average time, in milliseconds, that the packet listener spent processing a packet.
The number of packets processed by that packet listener since the packet listener
registered.
