public class ProtocolCommandEvent
extends EventObject
There exists a large class of IETF protocols that work by sending an
ASCII text command and arguments to a server, and then receiving an
ASCII text reply. For debugging and other purposes, it is extremely
useful to log or keep track of the contents of the protocol messages.
The ProtocolCommandEvent class coupled with the
ProtocolCommandListener interface facilitate this process.
