Class kmy.net.ftpd.FTPDConnection 

kmy.net.ftpd.FTPDConnection
public class FTPDConnection
Class FTPDConnection encapsulates a single FTP connection to the server. This class is running while connection is open. It processes FTP commands as they are received from the client. The main trick that most commands are translated to the calls to the corresponding methods of this class using Java reflection. Specifically, all methods that have the following signature: 
     public String XXXX( String arg );
will become valid FTP commands. (XXXX is a sequence of upper-case letters, digits or '_'. Also, names like SITE_XXXX will become accessible as SITE commands. HELP strings can be added using public members of type String that have names like XXXX_HELP.

Constructors

o FTPDConnection 
 public FTPDConnection(FTPDaemon sr,
                       Socket sk) throws IOException
Create new FTP connection for the specified server on the specified socket.

Throws: IOException
if was not able to set socket options and set up input-output streams

Methods

o debug 
 public final boolean debug()
Convenience method: used to obtain server's debug flag.

o getDataType 
 protected String getDataType()
Get the String that represents current data transfer mode.

o buildDataConnection 
 public Socket buildDataConnection(String name,
                                   String dataType,
                                   long bytes) throws Exception
Builds data connection using either previous PORT command data or passive mode port. On success sends "150" FTP reply to the client.

Throws: Exception
if cannot connect to the port specified in port command or listening on the "passive" socket produced an exception or if neither PORT nor PASV commands were given.
o nextChallenge 
 protected String nextChallenge()
Produces new challenge that is sent to the client as a part of the request for the password and can be used for authentication. Override this method if you want to generate challenge yourself.

o nextRandom 
 public long nextRandom()
Returns next long random value. This can be used to generate challenge.

o makePath 
 protected String makePath(String name)
Creates a path that represents a resource referenced by 'name'. The resulting path takes into account current working directory of this connection.

o run 
 public final void run()
Processes commands sent by the client. Commands QUIT and SITE are processed directly, the rest is processed using java reflection call to the corresponding "String XXX( String arg )" method.
