| org.archive.net.ClientFTP
| ClientFTP | | public class ClientFTP extends FTPClient (Code) | | Client for FTP operations. This class is necessary only because the
ClientFTP._openDataConnection_(int,String) method is protected in
the superclass, and we need to call it directly to handle directory
listings. (The code that provides directory listings in the
superclass doesn't scale: It reads the entire directory into
an in-memory list).
Additionally, "strict" methods are provided for the other operations
we use. Maddeningly, the superclass never raises exceptions. If an
FTP operation fails, then the superclass methods generally return false.
A developer then needs to check the
FTP.getReplyCode method to see what actually went wrong. The "strict" methods provided
by this class invoke the superclass method, check if the success flag
is false, and then raise an
FTPException with the value of
FTP.getReplyCode .
