If you can manage to do that, you could then create an object of your
new class and use that to connect.
Net::FTP::Recursive creates five new methods: rget, rput, rls, rdir,
and rdelete. Net::FTP::AutoReconnect does its work by creating new
methods with the same name as the Net::FTP methods, and wrapping them
in its own _autoreconnect() subroutine. From what I can tell, you
would have to create a class that inherits from both classes, and
redefines Net::FTP::Recursive's five methods the way
Net::FTP::AutoReconnect redefines Net::FTP's.
You would also have to implement a constructor that does the
functionality of both modules' new() methods.
While none of this is exactly trivial, I think it should be possible.
To get you started, you need to read up on classes and inheritance.
Read thoroughly:
perldoc perltoot
perldoc perlmod
perldoc perlmodlib
The basic syntax you'll want to start your new class will look
something like this:
package Net::FTP::RecAutoRec;
use strict;
use warnings;
use Net::FTP::AutoReconnect;
use Net::FTP::Recursive;
our @ISA = qw(Net::FTP::AutoReconnect Net::FTP::Recursive);
Hope this helps,
