Interface ProtocolCommandListener
- EventListener
public interface ProtocolCommandListener
extends EventListener
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 ProtocolCommandListener interface coupled with the
ProtocolCommandEvent
class facilitate this process.
To receive ProtocolCommandEvents, you merely implement the
ProtocolCommandListener interface and register the class as a listener
with a ProtocolCommandEvent source such as
FTPClient
.
ProtocolCommandEvent
